Fees

Human-facing ledger (token address, Bankr LP split, hub wallets): Token & fees.

Hub swap fees (x402)

Protocol fee is taken as a second x402 accept on match pay (not skimmed from seller settlement off-band).

Defaults (env):

  • FEE_BPS — basis points of the matched price (e.g. 500 = 5%)
  • MIN_FEE_USDC — floor (e.g. 0.001)
  • HUB_PAY_TO — fee recipient (Base)
  • HUB_PAY_TO_SOLANA — fee recipient (Solana)
  • Asset: USDC via x402 on Base and Solana

Settlement is x402 USDC on both Base and Solana. That does not change the dual-payee split.

Exact live values: GET https://api.curb.numetal.xyz/.well-known/x402 and the 402 body on POST /v1/matches/{id}/pay.

$CURB LP / trading fees

Two layers (see /fees):

  1. LP / protocol (Bankr Doppler, on-chain): creator share 95% to the goekhan Bankr EVM fee claimer; 5% protocol/platform.
  2. Distribution (creator-side, same policy as $NUMETAL): claimed fees split WETH 80% team / 10% treasury / 10% burn and $CURB 40% team / 30% treasury / 30% burn.
