Cross-Chain dApp Building: Live on Mainnet

Deploy once.
Read every chain.

Deploy Attestcoin Smart Contracts on Creditcoin to read and verify transaction data from any supported blockchain with cryptographic proofs, without a centralized single point of failure.

One contract.
Every chain.

The Attestcoin Protocol is a general-purpose cross-chain execution layer built into Creditcoin's runtime. Your Attestcoin Smart Contracts (ASC) natively read, verify, and act on data from any supported chain, without trusting a bridge or oracle operator.

No bridges
or oracles.

Bridges concentrate risk. Centralized oracles can be corrupted. The Attestcoin Protocol eliminates both, with trust distributed across a decentralized network of independent attestors. No single point of failure.

Synchronous
verification

Proofs verified in the same transaction, one block (~15 seconds). No async waiting, no intermediate state, no multi-step flows. Results available immediately.

General-
purpose

DeFi, gaming, RWA, governance, bridges — if it involves cross-chain data, the developer tools on the Creditcoin network handle it. Write Solidity with your existing tooling. No vendor lock-in.

Four components.
One seamless flow.

01

Deploy

Your Source Chain Contract (e.g. Ethereum) handles source-side logic and emits events with the data you need to verify.

e.g. Ethereum / Sepolia
02

Prove

Your Oracle Worker monitors events, waits for attestation, and auto-generates Merkle + continuity proofs.

off-chain automation
03

Verify

Your Attestcoin Smart Contract on Creditcoin verifies proofs cryptographically via the native precompile, synchronously, same transaction.

~1 block / ~15 seconds
04

Execute

Business logic fires immediately. Users sign once. The worker handles retries, deduplication, and proof formatting automatically.

Running since 2017.
Not a whitepaper.

The infrastructure you're building on has processed millions of real-world financial transactions, load-tested in production for nearly a decade.

The difference

Infrastructure + Ecosystem

Most L1s offer infrastructure. Creditcoin offers infrastructure plus funding, community, and distribution, so you can focus on building, not bootstrapping.
