Anchor Introduction

Anchor is a framework for Solana’s Sealevel runtime providing several convenient developer tools.

Install and Config

Reference: Getting started with Solana and Anchor

• install rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

export PATH="$HOME/.cargo/bin:$PATH"

• install solana

sh -c "$(curl -sSfL https://release.solana.com/v1.11.10/install)"

export PATH="$HOME/.local/share/solana/install/active_release/bin:$PATH"

• install anchor

cargo install --git https://github.com/project-serum/anchor anchor-cli --locked

anchor --version

• install yarn

npm install -g yarn

yarn install

• solana config

URL for Solana's JSON RPC [mainnet-beta, testnet, devnet, localhost]

solana config set --url localhost

• getnerate key pair

solana-keygen new

solana address

Run a local ledger

run a local ledger for development and testing.

# Check you can run a local validator (Run Ctrl+C to exit).
# Note this creates a "test-ledger" folder in your current directory.
sudo solana-test-validator

# Or, run a new empty local ledger.
sudo solana-test-validator --reset

First Time Build

cd router-solana-contract

sudo anchor build  

Once our code was compiled, the target folder was updated accordingly.

The target folder basically keeps track of any built releases and deployment of our program.

Especially

target/deploy

The first time you build a program, it will also generate a public and private key for it — which will be stored in the target/deploy directory. The public key generated will become the unique identifier of your program (the program ID). It also inclue a .so file which is the compiled BPF program.

target/idl

simply a JSON file that contains all the specifications of our Solana program

Update program ID

We can access our program ID by using the following Solana command.

solana address -k target/deploy/router-keypair.json
# Outputs something like: 5F3j1TvB7CQa4XRFN48iAd8y2ZgXXzUTVMJvtFXvF4N

Okay now that we know our program ID, let's update it.

First, in our Anchor.toml configuration file.

[programs.localnet]
router = "5F3j1TvB7CQa4XRFN48iAd8y2ZgXXzUTVMJvtFXvF4N"

Then, in the lib.rs file of our Solana program. that's programs/router/src/lib.rs.

declare_id!("5F3j1TvB7CQa4XRFN48iAd8y2ZgXXzUTVMJvtFXvF4N");

Build
