Multi-Chain Architecture
The Infestation Spreads
RatBastards is natively multi-chain from day one. Not a bridge afterthought - a core architecture decision. And this is just the beginning. The sewer network can expand to any EVM chain.
Starting Chain Distribution
These are our 5 launch chains. More sewers can be opened based on community demand and strategic opportunities:
| Chain | Token IDs | Status |
|---|---|---|
| Base | 1 - 2,000 | Live (Testnet) |
| Monad | 2,001 - 4,000 | Planned |
| HyperEVM | 4,001 - 6,000 | Planned |
| Ape Chain | 6,001 - 8,000 | Planned |
| Ethereum | 8,001 - 10,000 | Planned |
Cross-Chain Uniqueness
Here's the big brain shit: Sparse Merkle Trees (SMT) ensure no two rats can have the same trait combination across ANY chain.
- >Non-inclusion proofs verify global uniqueness in real-time
- >Backend coordinates tree updates across all chains
- >Zero duplicate rats - ever. Across all chains.
- >Novel approach to cross-chain state that's never been done like this
LayerZero Bridge System
We're integrating LayerZero for trustless cross-chain messaging. Here's how it works:
- >LayerZero's omnichain protocol handles secure message passing between chains
- >Your NFT is burned on source chain and re-minted on destination
- >Trait data travels with the message - your rat stays identical (unless you mutate)
- >Decentralized Verifier Networks (DVNs) validate cross-chain transactions
- >No centralized bridge - just pure protocol-level interoperability
Bridge Types
| Bridge Type | Cost | Effect |
|---|---|---|
| Free Escape | LayerZero fees only | Move to another chain, keep same rat |
| Single Trait Mutation | [REDACTED] | Mutate one trait during bridge |
| Full Mutation | [REDACTED] | All 5 traits regenerated on arrival |
Bridge Mechanics
Every bridge action updates on-chain counters that track your rat's journey:
- >Escape Counter: Total number of cross-chain bridges
- >Mutation Counter: Number of trait mutations performed
- >Both are visible on-chain - a permanent record of your rat's history
- >Bridge revenue is split across creators (artists and holders) of each trait your rat wears
"Your rat. Your journey. On-chain forever."
