Deploy Aztec contracts

# Navigate to the Aztec monorepo
cd ~/nargo/github.com/AztecProtocol/aztec-packages/v0.87.2/noir-projects/noir-contracts/

# Compile the token_contract package
aztec-nargo compile --package token_contract

# Return to the root of the project directory

# Copy the compiled artifact back to your project
cp ~/nargo/github.com/AztecProtocol/aztec-packages/v0.87.2/noir-projects/noir-contracts/target/token_contract-Token.json ./target/token_contract-Token.json

If you see the following error when compiling:

src/artifacts/Token.ts:26:3 - error TS2305: Module '"@aztec/aztec.js"' has no exported member 'L1EventPayload'.

Go to src/artifacts/Token.ts and remove the L1EventPayload import.
