You can also import the [type-safe ABI](https://abitype.dev/) from the `/abi` path.

```ts
import {
    // standard version
    lsp8IdentifiableDigitalAssetAbi,
    lsp8CappedSupplyAbi,
    lsp8MintableAbi,
    lsp8VotesAbi
    // proxy version
    lsp8CappedSupplyInitAbstractAbi,
    lsp8IdentifiableDigitalAssetInitAbstractAbi,
    lsp8MintableInitAbi,
 } from '@lukso/lsp8-contracts/abi';
```

## Foundry deployment

This package includes a Foundry script at `scripts/DeployLSP8CustomizableTokenInit.s.sol` to deploy the `LSP8CustomizableTokenInit` implementation contract.

Set your deployer key first:

```console
export PRIVATE_KEY=0x...
```

## Dry run against LUKSO Testnet

```console
FOUNDRY_PROFILE=lsp8 forge script packages/lsp8-contracts/scripts/DeployLSP8CustomizableTokenInit.s.sol:DeployLSP8CustomizableTokenInitScript --rpc-url https://rpc.testnet.lukso.network
```

## Broadcast the deployment

> Use one of the methods described in the [foundry docs](https://www.getfoundry.sh/forge/scripting#providing-a-private-key) to broadcast from a specific address

```console
FOUNDRY_PROFILE=lsp8 forge script packages/lsp8-contracts/scripts/DeployLSP8CustomizableTokenInit.s.sol:DeployLSP8CustomizableTokenInitScript --rpc-url https://rpc.testnet.lukso.network --broadcast
```

Broadcast and verify on the LUKSO Testnet Blockscout explorer:

```console
FOUNDRY_PROFILE=lsp8 forge script packages/lsp8-contracts/scripts/DeployLSP8CustomizableTokenInit.s.sol:DeployLSP8CustomizableTokenInitScript --rpc-url https://rpc.testnet.lukso.network --broadcast --verify --verifier blockscout --verifier-url https://api.explorer.execution.testnet.lukso.network/api?
```
