IPCImmediate Finality
The L2 subnet uses CometBFT-style block commit — every committed block is final. No probabilistic waiting, no reorg risk. Cross-chain message delivery is bounded by validator checkpoint signing, not L1 reorg windows.
The Interplanetary Consensus L2 Platform
Fast, cheap, and interoperable by design.
IPC is an EVM-compatible L2 that combines immediate finality, low-cost stablecoin-denominated gas, a dual EVM + CosmWasm runtime, and first-class cross-chain messaging — built for ecosystem partners that need to move fast without sacrificing architecture.

Why IPC
Built around the properties that matter
Four architectural decisions that separate IPC from a generic EVM L2.
Low, Predictable Gas
Gas is stablecoin-denominated, keeping transaction costs stable and predictable for applications and their users.
EVM + CosmWasm Runtime
Build Solidity contracts today and deploy CosmWasm contracts for richer on-chain logic when you need it — both running on the same chain, with the same block and finality guarantees.
Chain-Native Precompiles
EVM applications can call bank, staking, distribution, ERC-20, and IBC module functions directly through precompile addresses — no external bridge or wrapping contract required.
Feature highlights
Capabilities proven in the stack
Each feature maps directly to working implementation and scripted test paths.
Live
Cross-chain messaging
Dispatch arbitrary byte payloads between EVM-compatible chains. Proven end-to-end via raw message and PingPong contract-to-contract round-trips.
Live
Asset bridging
A stablecoin ERC-20 moves between chains via a Hyperlane warp route: collateral locked on the origin, synthetic minted on the L2. Deposit and withdraw paths fully scripted.
Live
Dual EVM + CosmWasm runtime
The same chain binary exposes full EVM JSON-RPC alongside CosmWasm and Cosmos REST — one environment for Solidity and WASM contract developers.
Live
Precompile-powered modules
Static precompiles for bank, staking, distribution, ERC-20, and IBC are activated at genesis. EVM contracts call chain-native functionality without wrapping.
Live
Full observability stack
Blockscout for EVM transaction inspection, a Hyperlane Explorer for per-message traces, and a live message-log dashboard — all opt-in via a single make target.
Dev-ready
Reproducible partner stack
Docker, Foundry, and jq are the only host dependencies. No Node.js required. The entire environment — chains, agents, explorers — is brought up with one command.
All features backed by working implementation in the open repository.
How it works
A four-step cross-chain message pipeline
Every asset transfer and arbitrary message follows the same path: dispatch, sign, relay, execute.
DispatchOrigin
App calls Mailbox.dispatch() on the origin chain. Mailbox emits a message and updates the merkle tree.
SignValidators
Hyperlane validators observe the new merkle root and publish signed checkpoints to their storage syncer.
RelayRelayer
The relayer assembles a multisig proof from validator checkpoints and calls process() on the destination Mailbox.
ExecuteDestination
The ISM verifies the proof, then the Mailbox calls handle() on the recipient contract with the original payload.
Trust and scope
Testnet launching soon
We are launching our testnet and will publish connection details shortly. The architecture is built for rapid iteration — every design decision and upcoming milestone is documented openly.
Current v1 constraints
- Multi-validator bridge with a clear path to independent operator federation.
- Validator checkpoints moving to S3-synced independent operators in the next milestone.
- Interchain Gas Paymaster contracts are deployed and will be activated on testnet.
Production roadmap
- v1.1S3 checkpoint syncers + KMS validator keys + IGP enforcement
- v1.2Real Filecoin Calibration deployment + reorg-period tuning
- v2Fraud-window withdrawals + bonded ISM economic security
- v3On-chain slashing + IBC Eureka alternate bridge path
