Seltra

What it is

Seltra is a limit-order protocol on Avalanche C-Chain. Orders live in your wallet. You do not deposit into Seltra to wait for a fill.

What it does

Sign a gasless order. Keepers try to fill it from aggregated DEX liquidity, or another Seltra trader can take the other side. Cancel one order or wipe every open order in a single transaction. Settlement is immutable, no upgrade key on your fills.

Why it is different

Your price or better: the contract will not fill worse than your limit, and you keep 70% of any surplus. No standing token approvals to Seltra, movement happens through Permit2 and the signature you already gave.
