Getting started

Install

• Install Rustup
• Install dependencies

yarn install

• Install solana

curl -sSfLO https://github.com/anza-xyz/agave/releases/download/v2.0.14/solana-release-x86_64-unknown-linux-gnu.tar.bz2
bunzip2 solana-release-x86_64-unknown-linux-gnu.tar.bz2

Build

• Get correct transfer-hook contract address

yarn keys-list

• Set contract address in Anchor.toml and uncomment this line

#transfer_hook = "<transfer hook address returned by 'yarn anchor keys list'>"

• Set contract address in programs/transfer-hook/src/lib.rs

declare_id!("<transfer hook address returned by 'yarn anchor keys list'>");

• Build project

yarn build

Test

• Define needed keys in the environment

export SOLANA_REGISTRAR_PRIV=<private key for registrar role>
export SOLANA_TECHNICAL_PRIV=<private key for technical role>
export SOLANA_OPERATIONS_PRIV=<private key for operations role> 

• Start local blockchain

solana-test-validator -r > validator_log &

• Run integration tests

yarn test

Deploy transfer hook on solana devnet

• First write the buffer

solana program write-buffer ./target/deploy/transfer_hook.so --use-rpc -ud

• Get the buffer address from the output of previous command. e.g.

$ solana program write-buffer ./target/deploy/transfer_hook.so --use-rpc -ud
Buffer: Cg7aThjZFxUNpUHrn11BcfJh795Yt5mpHXAB1G2f1o5k

• Then deploy the program

solana program deploy --buffer <address from previous command> -ud --program-id ./target/deploy/transfer_hook-keypair.json --use-rpc

Close program account to reclaim SOL

solana program close <ProgramId> -ud --use-rpc

Deploy Smartcoin token on solana devnet
