How Halyard works

Overview

Halyard is a fee bridge for pump.fun. A token points creator fees at a Halyard fee address. Collections are credited in full and withdrawn in USDC.

Supported accounts are X, Spotify, Twitch, GitHub and FOMO. The recipient signs in with that same account.

Fees are collected from pump.fun bonding curves and from PumpSwap after graduation.

The pump.fun creator field is set to the Halyard fee address for the named account and stays fixed for the life of the coin.

The coin description carries one line: Fees to @yourhandle via Halyard.

100% of every claim is credited to the named creator. Halyard does not keep a share of creator fees.

A keeper collects accrued creator fees on a schedule and writes the credit on chain.

The creator signs in and withdraws USDC. The network fee for that withdrawal is paid by the keeper wallet.

X, Spotify, Twitch and GitHub balances wait for the account to withdraw. FOMO balances are sent to the trading wallet.

Fee addresses are derived from the stable platform account id, so a rename does not move the money.

Halyard does not pay through X Money. There is no public payment interface there. Credits stay on Solana.

Every claim and payout is listed on the transparency desk with its transaction.

Fees may arrive as SOL. They are swapped to USDC before the creator withdraws.

An unclaimed balance stays credited to the named account until that account withdraws or opts out.

The named account can ask to stop being listed. FOMO pushes stop when the request is accepted.

A coin appears after its create transaction confirms and the fee address matches a named account.
