The EXM contract below is an example implementation of a contract that uses TON network for contract's caller authentication (action.caller), empowered by ton-auth atom of ton molecule.
- Live deployment: lpLm1AKAhY-AZPMFwXVOLkMe7UDtaoNiG3keNMJEapg
- source code: ./contract.js
- EXM SDK
npm i -g @execution-machine/sdk- EXM API token ID: visit exm.dev
To register a name in the contract example, you have first to sign with your wallet the message used for verification in the contract's example which is hello world
signature and caller (publicKey) should be both converted to Uint8Array then encoded in base64 before passing them in to the atom (therefore the example contract input key-value pairs).
// molecule.sh accepted input format
const message = btoa("hello world");
const moleculePubKey = btoa(new Uint8Array(publicKey));
const moleculeSig = btoa(new Uint8Array(signature));
// GET http://ton.molecule.sh/ton-auth/{moleculePubKey}/{message}/{moleculeSig}
