• Get pending transactions: Get all pending transactions.

• Confirm transaction: Accept a transaction. Fot that purpose a valid signer|owner of the safe must be provided.

• Postman collection could be found on /src/postman.

Safe-SDK initialization

1. Create Ethers Adapter: You will have to provide a signer or provider to sign or view transactions from the SafeAPIKit.

return new EthersAdapter({
  ethers,
  signerOrProvider: safeOwner
})

2. Create SafeAPIKit: Using the ethersAdapter and the Transaction Service URL you will initialize your safeService. For the complete list of the safe transction services url please refer to: https://docs.safe.global/learn/safe-core/safe-core-api/available-services

const safeService = new SafeApiKit({ txServiceUrl, ethAdapter: adapter })

3. Create Safe Factory:

const safeFactory = await SafeFactory.create({ ethAdapter: adapter })

4. Initialize SafeSDK: Here you will need to provide your Safe public Address

await Safe.create({
  ethAdapter: this.adapter,
  safeAddress: address
})

Query request example with TRPC

• Get your input formatted where INPUT is a URI-encoded JSON string.

const tRPC2 = encodeURIComponent(JSON.stringify('hola'))

curl --location 'localhost:2021/trpc/greet?input=%2522hola%2522'
