Send a transfer between two accounts with a memo to remind you about why you made a transaction. The actual program is deployed on the devnet currently. This repo has a js client you can use, and a demo that you can spin up (basic nexjs app to interface with the client).

Demo: https://memo-1zeh8izw6-strangemood.vercel.app/

import {
  getLastMemos,
  getMemoAccountForPubkey,
  getMemoProvider,
  transferWithMemo,
} from "@strangemood/memo";

const currentWalletMemoAccount = getMemoAccountForPubkey(
  `wallet address of a user, likely the current authed user`
);

import * as anchor from "@project-serum/anchor";
import { memoIDL, DEVNET } from "@strangemood/memo";

// get connection and wallet however you'd like... you can look at inspo in demo/MemoExample.tsx

const provider = new anchor.Provider(connection, wallet);
const program = new anchor.Program(idl, DEVNET.MEMO_PROGRAM_ID, provider);
const tx = await program.rpc.memoTransfer(
  utf8encodedMemo,
  new anchor.BN(transferData.amount),
  {
    accounts,
  }
);

To use the program it needs to be deployed. This is currently running on the devnet but can be deployed on mainnet whenever.

1. Building and Deploying:

anchor build anchor deploy

2. Running the build command above, generates an updated idl file. This is managed by Anchor and helps in building the JS client. To make sure the JS client is using a compatible interface to the program on chain, copy the target/idl/memo.json file into client/src/memo.json.

Create a local symlink so you can develop without new npm publishing.

1. cd client, yarn build, yarn link

2. cd demo, yarn link @strangemood/memo
