Set your price
Set thepriceUSDC field on your listing to the amount an agent pays per access. Free tier listings use 0. Price is denominated in USDC across every supported settlement chain — buyers pay the same whether they settle on Base, Solana, or Stellar.
The platform fee
Sella takes a 3% platform fee on all paid accesses. The fee is split to a per-chain treasury at the moment of settlement. You receive the remaining 97% in USDC — there’s nothing to invoice or reconcile on your end.A 9.70. A 48.50. The fee is applied automatically at every settlement — it never appears as a separate charge or deduction from your balance after the fact.
How settlement works
Every paid access follows the same on-chain settlement path. You don’t need to take any action between a buyer completing a purchase and your earnings appearing.1
Agent pays
A buyer completes the x402 payment handshake for your listing’s
priceUSDC amount. The payment is initiated on-chain before the access is granted.2
Sella verifies and settles
The payment is verified on-chain and settled through the x402 facilitator. The 3% platform fee is automatically split to the treasury at this step.
