Bridges get hacked. Centralized oracles can be corrupted or go offline. Both create single points of failure that put your users' funds at risk. The Attestcoin Protocol eliminates trust assumptions entirely. Your contracts natively verify cross-chain data using cryptographic proofs, not intermediaries.
The Attestcoin Protocol is the cross-chain layer built into Creditcoin's runtime. Creditcoin is the Layer 1 you deploy on.
To read data on other blockchains, you deploy Attestcoin Smart Contracts on the Creditcoin L1.
This cross-chain building is secured by a decentralized network of independent Attestors rather than a bridge operator or a single oracle.
For years, cross-chain meant choosing between security and functionality. The Attestcoin Protocol removes that choice.
Most bridges measure latency in minutes. The Attestcoin Protocol verifies in a single block.
The Attestcoin Protocol is built into Creditcoin's runtime. The attestation infrastructure is native, which means verification runs as compiled Rust code at the protocol level.
No operator keys to compromise. Proofs are verified mathematically, if they pass, the data is real. If they don't, the transaction reverts.
Verification and business logic execute in the same transaction. No async callbacks, no multi-step UX, no waiting for confirmations.
Write Solidity. Use Hardhat, Foundry, your existing toolchain. No new languages, no vendor lock-in, no migration overhead.
Verify up to 10 cross-chain queries in a single transaction with a shared continuity proof. Efficient at any scale.
Your Source Chain Contract handles source-side logic and emits events with the data you need cross-chain.
e.g. EthereumYour Oracle Worker monitors events, waits for attestation, and auto-generates Merkle + continuity proofs.
off-chain automationYour Attestcoin Smart Contract on Creditcoin calls the native precompile. Proofs verified cryptographically in the same transaction.
~1 block / ~15sBusiness logic fires immediately. Users sign once. The worker handles retries, deduplication, and proof formatting.
seamless UXThe Attestcoin Protocol is general-purpose, any use case involving cross-chain data is fair game. Here's where developers are already building.
Access liquidity and users across every supported chain from a single contract. Build lending, borrowing, yield, and trading applications without trusting a bridge to move assets.
Tokenize, finance, and manage real-world assets on Creditcoin. The Attestcoin Protocol gives you the cross-chain data layer to bridge off-chain value with on-chain transparency.
Build coordination layers for physical infrastructure networks, IoT, telecom, storage, satellite. Use Creditcoin for incentives, service verification, and settlement across networks.
Power in-game asset ownership, player-driven economies, and cross-chain item portability. Give players real ownership of in-game assets that exist and are verifiable across chains.
You don't need to apply for anything to start building. Get testnet CTC from the faucet in our Discord, spin up the tutorial, and have a working cross-chain dApp running before you've filled out a single form.
Head to the 🚰 faucet channel and request CTC tokens. Free, instant, no KYC.
Watch the videos, then clone the example repo and deploy your first Attestcoin Smart Contract. A working cross-chain dApp reading Sepolia from Creditcoin testnet takes under an hour.
When you're ready to go live, CEIP can fund your journey and prepare you to launch to our active ecosystem community.
When you're ready to move beyond testnet, two programs accelerate the path from idea to funded, launched product.
CEIP is a $10M investment initiative led by Credit Labs. Open to any team, startups or established builders, with a vision for what can be built on Creditcoin.
Creditcoin's hackathon series across 4 tracks: DeFi, RWA, DePIN, and Gaming. The top 3 teams fast-track directly into CEIP, bypassing initial screening and going straight to due diligence.
Everything you need to leverage the Attestcoin Protocol for cross-chain dApp building is in the docs. Join Discord to get testnet tokens and ask questions in real time.
