This snap helps you interact with Mina protocol using MetaMask
npm install mina-snapThis snap helps you interact with Mina protocol using MetaMask
Important
Please install MetaMask before using this snap.
shell
yarn install
`
Building
Run to build this snapRun
yarn build:clean to remove old dist folder and re-build snapStart local snap
Note: To interact with the snap hosted on your local machine, you will need to use MetaMask Flask and make sure to disable the normal MetaMask before using the Flask version.Run
yarn serve to start local snapThe snap will be running on
http://localhost:8080. You can change port number in snap.config.js as wellYour DApp now can connect to the snap by calling
wallet_requestSnaps method with http://localhost:8080 as the snapId(Reference: https://docs.metamask.io/guide/snaps-rpc-api.html#wallet-requestsnaps)
Using published snap
Connect to the snap by calling wallet_requestSnaps method with npm:mina-portal as the snapIdNotes
- Babel is used for transpiling TypeScript to JavaScript, so when building with the CLI,
transpilationMode must be set to localOnly (default) or localAndDeps.
- For the global wallet type to work, you have to add the following to your tsconfig.json:
`json
{
"files": ["./node_modules/@metamask/snap-types/global.d.ts"]
}
`Publish snap to NPM
- Update the in package.json then run:
`
yarn build
- Run the below command to publish to NPM:
npm publish

Implement ZkApp transaction
- To make ZkApp transactions with your smart contract, you will need to have the built file of the smart contract (the .js file).
- Install on your front-end site and use o1js to make the transaction.
- Then submit your transaction using snap.Here is an example:
`
import {
Mina,
PublicKey,
fetchAccount,
Field,
} from 'o1js';(async() => {
const { } = await import();
const zkAppAddress =
const graphqlEndpoint =
const zkApp = new (PublicKey.fromBase58(zkAppAddress));
Mina.setActiveInstance(Mina.Network());
.compile();
const account = await fetchAccount({publicKey: zkAppAddress, ...zkApp}, );
const tx = await Mina.transaction({
sender: PublicKey.fromBase58(),
fee:
}, () => {
zkApp.update();
});
const provedTx = await tx.prove();
await ethereum.request({
method: 'wallet_invokeSnap',
params: {
snapId: ,
request: {
method: 'mina_sendTransaction',
params: {
transaction: tx.toJSON(),
feePayer: {
fee: ,
memo: ,
}
}
},
},
});
})();
