Referrals

Values as of 2026-11-10; they can change. Referrals are built into the Knockout program on Solana. Every rule here is a rule of that program, and every value lives on chain.

In short


Referrer	A wallet that registers a referral record. The record collects the referrer’s share.
Link	A wallet links itself to one referrer, by its own signature. The link is for life.
Discount	A linked wallet pays 10 % less exit fee. A link made before 2026-11-10 keeps 25 %. The rate is fixed into the link when the link is made.
Referrer’s share	A part of the protocol’s share of each settled trade of a linked wallet. The rate starts at 20 % and rises in tiers, up to 50 %.
Which trades count	For the share, only trades committed at or after the moment of the link. For the discount, every close settled after the link exists.
Claim	The record’s owner withdraws the credited share in USDC, at any time.

Becoming a referrer

A wallet registers a referral record with register_referral_account. The wallet signs, and any payer can pay the rent of the record. Each wallet can register one record. A record does not need a trading account first. The wallet that signs is the record’s authority: it claims the share. The authority can hand the record to another wallet with set_referral_authority. The record’s address does not change, and its links stay with it.

Linking a wallet to a referrer

A wallet links itself to a referrer’s record with set_referral.

Only the wallet can link itself. The link is made for the wallet that signs. A payer can pay the rent, but nobody can link a wallet that is not theirs.
One link, for life. A wallet has at most one link. Once made, the link cannot be changed, moved to another referrer or removed. A second link for the same wallet is refused.
A wallet cannot refer itself. A link to a record whose authority is the same wallet is refused.
The link can be made in its own transaction or in the same transaction as a trade.

The referrer argument of open is not a referral link. It moves no money and creates no link.

The discount

A linked wallet pays a lower exit fee. The discount is a share of the exit fee: 10 % off the fee the close would pay without a link. A link made before 2026-11-10 keeps its 25 % off.

Fixed in the link. The discount rate is copied into the link when the link is made, and it never changes. A later change to the program’s discount setting applies only to links made after it.
Every close after the link. The discount applies to every close of the wallet’s positions that settles after the link exists. The time the position opened does not change this.
Only where there is a fee. A knockout pays no exit fee, so it has no discount. The same holds for any other close that pays no exit fee.
It comes out of the protocol’s part of the fee. The pool’s part of the fee does not change.

Each discounted close emits a ReferralDiscounted event. It carries the fee without the discount (fee_full) and the amount saved (discount). The fee actually charged is on the close’s SettlementReceipt event (exit_fee_total), so fee_full is exit_fee_total plus discount. When a linked wallet’s trade settles, the referrer’s record is credited a share of the protocol’s part of that settlement: the protocol’s part of the exit fee, after the discount, and the protocol’s part of the loss tax. The share is moved to the program’s referral vault and credited to the record.

Which trades earn. A trade earns the share only if it was committed at or after the moment the link was made. A trade committed before the link earns nothing, even if it settles later.
What the share is computed on. The share is computed on the protocol’s part that the settle actually pays. The protocol’s own part of a close is paid last, and not at all while any win is still owed (see how a win is paid). A settle that pays the protocol nothing credits no share.
The rate. The rate is the record’s tier. A record starts at the default tier and moves up as the revenue its linked wallets drive grows. That revenue is the record’s running total of the protocol’s part on which the share was computed.

Revenue driven by the record’s linked wallets (USDC)	Rate, share of the protocol’s part
Below 10,000	20 %
10,000	25 %
40,000	30 %
150,000	35 %
500,000	40 %
650,000	45 %
1,000,000	50 %

The tier rises when a record’s total crosses a line and the record is refreshed with refresh_referral. Anyone can send it, for up to twenty records at a time. The rate applied to each settle is on its event, and it is never more than half of the protocol’s part. Each settle of a linked wallet’s trade emits a ReferralAccrued event, after the settle’s other events. It names the record and the position, and carries:

Field	Meaning
`base`	The protocol’s part the share was computed on. 0 when the trade does not earn.
`amount`	The share credited to the record. 0 when the trade does not earn.
`rate_bps`	The rate applied, in basis points.
`tier_bps`	The record’s tier at the settle.
`base_total`	The record’s running total after this settle.

If the settle finds a fault at the referral accounts that the sender cannot cause, it emits ReferralSkipped instead, and the share goes to the protocol. A trade is never refused for it. The discount and the share are applied by the settle of the position, when the settle carries the wallet’s link and, for the share, the referrer’s record and the referral vault. A settle of a linked book that leaves them out can be refused (ReferralAccountsRequired, 6306); one that is not refused applies no discount and credits no share. If you settle your own positions, include the three accounts. config.referralFlags holds the program’s referral switches. One can stop the share for every link, one can stop the discount for every link, and one lets a settle of a linked book that leaves out the referral accounts be refused. A record can be disabled. A disabled record earns nothing more, its links stay, the wallets linked to it keep their discount, and it can still claim what it was credited.

Claiming

The record’s authority withdraws the credited share with claim_referral.

It names an amount, or 0 to take everything credited and not yet claimed. An amount above that is refused.
It pays into any USDC token account, except three: the referral vault itself, the pool’s vault account and the protocol’s treasury.
A claim with nothing to pay does nothing.
Credited money stays on the record until it is claimed. A claim has no waiting period.

Each claim emits a ReferralClaimed event with the amount and the record’s lifetime total claimed.

Minute players

A Minute round is a Knockout position held by a player account that Minute derives from your wallet. The link of the wallet is copied to that player account with bind_referral: the copy names the same referrer, the same moment of the link and the same discount. Anyone can send it, and the sender pays the rent. Only a wallet’s own link can be copied, so the copy always says what the wallet’s link says. Once the copy exists, a Minute round gets the discount and earns the share under the same rules as any other trade. A round settled before the copy exists has no discount and credits no share.

Using the SDK

The SDK builds every instruction a wallet signs here, derives every address and decodes every account and event. Addresses passed to a builder are hex (toHex); decoded addresses are hex; money is bigint in USDC base units. Each builder returns a BuiltInstruction: turn it into a web3.js instruction with ourInstruction, then simulate and send it as on the quickstart.

Become a referrer

The wallet signs. payer pays the rent of the record and can be the same wallet or an app.

import { type PublicKey } from '@solana/web3.js';
import { referralRecordPda, registerReferralAccount, toHex, type BuiltInstruction } from '@rekt-trading/1000x';

export function becomeReferrer(wallet: PublicKey, payer: PublicKey): { built: BuiltInstruction; record: PublicKey } {
  const built = registerReferralAccount({ referrer: toHex(wallet), payer: toHex(payer) });
  // The record's address comes from the wallet that registers it, and never moves.
  return { built, record: referralRecordPda(wallet).address };
}

Link a wallet, once

The wallet being linked signs; payer can be an app. The record is the one derived from the referrer’s registering wallet. Read the wallet’s link address first: if an account is there, the wallet is already linked for life and a second link is refused.

import { type Connection, type PublicKey } from '@solana/web3.js';
import {
  decodeReferralLink,
  referralLinkPda,
  referralRecordPda,
  setReferral,
  toHex,
  type BuiltInstruction,
  type ReferralLinkView,
} from '@rekt-trading/1000x';

/** The wallet's link, or null when it has none. A link never changes, so one read is enough. */
export async function readLink(connection: Connection, wallet: PublicKey): Promise<ReferralLinkView | null> {
  const info = await connection.getAccountInfo(referralLinkPda(wallet).address, 'confirmed');
  return info === null ? null : decodeReferralLink(new Uint8Array(info.data));
}

export function linkToReferrer(wallet: PublicKey, payer: PublicKey, referrerWallet: PublicKey): BuiltInstruction {
  return setReferral({
    referee: toHex(wallet),
    payer: toHex(payer),
    record: toHex(referralRecordPda(referrerWallet).address),
  });
}

readLink(...)?.discountBps is the discount frozen into the link.

Read a referrer’s earnings

referralEarnings returns what an earnings screen shows, from the record and the settings on chain. Show its fields; compute no amount of your own.

import { type Connection, type PublicKey } from '@solana/web3.js';
import {
  chainNowSeconds,
  decodeReferralConfig,
  decodeReferralRecord,
  referralConfigPda,
  referralEarnings,
  referralRecordPda,
  type ReferralEarnings,
} from '@rekt-trading/1000x';

/** Null when the wallet has no record. */
export async function readEarnings(connection: Connection, referrerWallet: PublicKey): Promise<ReferralEarnings | null> {
  const [record, config] = await connection.getMultipleAccountsInfo(
    [referralRecordPda(referrerWallet).address, referralConfigPda().address],
    'confirmed',
  );
  if (!record || !config) return null;
  return referralEarnings(
    decodeReferralRecord(new Uint8Array(record.data)),
    decodeReferralConfig(new Uint8Array(config.data)),
    await chainNowSeconds(connection), // the chain's time, never your machine's
  );
}

Field	Meaning
`claimable`	What a claim pays now: credited less claimed.
`accrued`, `claimed`	Lifetime credited, lifetime claimed.
`tierBps`	The record’s tier.
`rateNow.rateBps`	The rate on the next settle.
`revenueDriven`	The record’s running total that sets the tier.
`nextThreshold`	The next tier line, its rate and the revenue still to drive; `null` at the top.
`referees`	The wallets linked to the record.
`refreshOwed`	The total has crossed a tier line that the record does not show yet. Send `refreshReferral([toHex(record)])`; anyone can.

Claim

The record’s authority signs. destination is a USDC token account, for example the wallet’s associated token account. An amount of 0n claims everything credited and not yet claimed.

import { type PublicKey } from '@solana/web3.js';
import { claimReferral, toHex, type BuiltInstruction } from '@rekt-trading/1000x';

export function claim(authority: PublicKey, record: PublicKey, destination: PublicKey, amount = 0n): BuiltInstruction {
  return claimReferral({ authority: toHex(authority), record: toHex(record), destination: toHex(destination) }, amount);
}

setReferralAuthority({ authority, record }, newAuthority) hands the record to another wallet.

Settling your own positions

A settle applies the discount and the share only when it carries the referral set: the owner’s link, the record it names and the referral vault. Pass the set as the referral argument of ix.settle, and compose the transaction through the table chooseSettleTable picks: a settle with the set fits only through the shared referral table.

import { type Connection, type PublicKey } from '@solana/web3.js';
import {
  chooseSettleTable,
  decodeReferralLink,
  referralLinkPda,
  referralSettleAccounts,
  toHex,
  type ChosenMarketTable,
  type ReferralSet,
} from '@rekt-trading/1000x';

/** The set for a book's owner, or null when the owner has no link. */
export async function referralSetFor(connection: Connection, owner: PublicKey): Promise<ReferralSet | null> {
  const info = await connection.getAccountInfo(referralLinkPda(owner).address, 'confirmed');
  if (info === null) return null;
  return referralSettleAccounts(toHex(owner), decodeReferralLink(new Uint8Array(info.data)).record);
}

/** The lookup table for the settle: the shared referral table when the set rides. */
export function settleTable(connection: Connection, market: PublicKey, set: ReferralSet | null): Promise<ChosenMarketTable> {
  return chooseSettleTable({
    market,
    referral: set !== null,
    required: [],
    fetchTable: async (address) => (await connection.getAddressLookupTable(address)).value,
  });
}

Then build the settle as on settling and pass the set: ix.settle(accounts, seq, reason, feeds, set). A settle of a linked book without it can be refused (ReferralAccountsRequired, 6306); one that is not refused applies no discount and credits no share. For a Minute round the owner is the player account, so read the player’s link.

Events

decodeReferralEvent(bytes) decodes any referral event and returns null for any other event. decodeReferralAccrued, decodeReferralDiscounted and decodeReferralClaimed decode one each.

Refusals

Error	Code	When
`ReferralClosed`	6305	Registration or linking is closed.
`ReferralAccountsRequired`	6306	A settle of a linked book left out the referral accounts. Pass the link, the record and the referral vault.
`ReferralSelfLink`	6307	The wallet tried to link to its own record.
`ReferralRecordDisabled`	6308	The record is disabled. Link to another record.
`NotReferralAuthority`	6311	The signer is not the record’s authority.
`ReferralClaimDestinationRefused`	6322	The claim named one of the three refused accounts. Name another USDC account.
`ReferralClaimTooLarge`	6323	The claim asked for more than is credited and not yet claimed.

A second link for the same wallet fails before the program’s own checks run, because the link already exists. Questions: support@asymmetra.xyz.
