One token. One Superchain.

Let's learn about SuperchainERC20s 🧵

Think of the Superchain as a network of cities (L2s), each with its unique features and communities.

Today, moving goods (assets) between these cities requires one to pass through uncertain borders, it is a hassle for developers and users alike.

SuperchainERC20 is an interface for crosschain tokens to move across the Superchain

Combined with native Interop, it will make the Superchain feel borderless.

Some examples of what this unlocks:

Imagine:

A token on chain A that can be used within a game on chain B

A token on chain C that gets lended on a pool in chain D

SuperchainERC20 expands the scope of token utility by allowing assets to access more ecosystems.

SuperchainERC20 + Superchain Interop will also unlock capital efficiency:

Today: $1M locked on 5 chains = $5M capital required

With SuperchainERC20 + Interop: $1M total = access across all chains

The magic? When you move tokens between eligible Superchain networks:

- They're destroyed (burned) on the source chain
- Created (minted) on the destination chain

No wrapping.

Just seamless movement.

SuperchainERC20's approach is complementary in aiding the operations of existing bridge providers:

- Implements ERC-7802 (a standard cross-chain mint/burn interface)
- No wrapped tokens
- No liquidity pools needed

Builders can deploy SuperchainERC20 compatible tokens right away, and get prepared for Superchain Interop.

This is recommended for all new tokens deployed on the Superchain in order to be interoperable on day one.

The future, once Superchain Interop is live, is:

- 2-second cross-chain settlement
- Minimized fragmentation
- Unified liquidity
- Maximum capital efficiency and utility

You can prepare for this by launching with the SuperchainERC20 standard today.

Some more examples:

- Mint an NFT on any chain from any chain
- Seamless chain-to-chain swaps with unified liquidity + low slippage
- Remove liquidity constraints from bridges
- Real-time cross-chain DeFi
- Novel arbitrage opportunities
- Cross-chain flash loans

Do I need to redeploy a new superchainerc20s token to replace my previous ERC20 token contract, or will my old ERC20 token be automatically compatible?
