Pisa allows users to pay for transaction fees, minimum ADA, and collateral using native tokens instead of ADA. The smart contract handles real-time token swaps behind the scenes and returns a ready-to-submit transaction. No changes to the Cardano ledger are required. SPOs are involved as normal, and there’s no batching – just seamless UX. Developers can integrate Pisa with a few lines of code via HTTP API or an upcoming NPM package.
