CTPDC · ATRIUM Data Connector

Cross-chain state, no trust bridge.

The ATRIUM Data Connector (ADC) is a decentralized protocol for trustless verification of state from external blockchains and the internet. Independent attestation providers observe outside networks and submit cryptographic proofs; once majority consensus (>50%) is reached, the event's state is finalized on CryptoTradePrime — powering cross-chain dApps and ADAssets bridging.

Consensus-enshrined

Capabilities

Cross-chain State Proofs

Validates events and state across Bitcoin, Ethereum, Solana, and Cosmos chains without wrapping or trust bridges.

Deterministic Routing

One contract interface verifies whether a remote event occurred — no off-chain relayer to bribe.

Slashing-secured

Validators attesting to state stake ATRIUM. False attestations are slashed by enshrined consensus.

Native Cross-chain Liquidity

Powers lock-mint and burn-release flows for CryptoTradePrime's canonical bridges and ATAssets issuance.

Proof Flow

Step 01

Request

A K-Chain contract calls `requestAttestation(chainId, txHash)` with a bounty.

Step 02

Attest

Validators observe the remote chain and submit signed attestations within one epoch.

Step 03

Settle

Consensus finalises the attestation. Contracts read it like any other state variable.
