Layer Details

Layer 1: Raw Data Collection

Direct blockchain data from 54+ networks via RPC endpoints. Network statistics, transaction counts, validator information.

Layer 1.5: RWA Context Layer NEW

Institutional macroeconomic data for RWA validation: World Bank (GDP, inflation), FRED (US economic data), UN Comtrade (trade flows), OWID (energy data), EMBER (grid carbon intensity).

Layer 2: Indicators

Calculated metrics: Carbon emissions (kg CO2/year), energy consumption (kWh), trade analysis, macro indicators.

Layer 3: Disclosure APIs

Regulatory-formatted responses for MiCA Article 66, CSRD/ESRS reporting, institutional ESG requirements.

Layer 4: DAP Protocol NEW

Disclosure Attestation Protocol - cryptographic proof of data delivery with timestamp anchoring and gas-optimized minting.

Layer 5: NFT Layer NEW

Polygon Mainnet smart contracts for API Access Passes, Compliance Certificates, and Attestation Records.
