## Digital Asset Control Atlas
- [Control Atlas](https://riadefi.com/atlas/): 47 asset grades and 13 chain grades.
- [Assets JSON](https://riadefi.com/atlas/assets.json): Complete machine-readable asset control registry.
- [Chains JSON](https://riadefi.com/atlas/chains.json): Complete machine-readable chain control registry.
- [ETH control profile](https://riadefi.com/atlas/assets/eth/): No issuer-level address freeze exists. Wallet, protocol, and chain dependencies can still constrain a particular position.
- [USDC control profile](https://riadefi.com/atlas/assets/usdc/): Yes. Circle administers the token contracts and can block addresses under its terms and applicable legal obligations.
- [USDT control profile](https://riadefi.com/atlas/assets/usdt/): Yes. Tether controls token issuance and address-blocking functions and has frozen addresses.
- [GHO control profile](https://riadefi.com/atlas/assets/gho/): No issuer blocklist is part of the asset profile. Governance can still change parameters and supporting mechanisms.
- [WBTC control profile](https://riadefi.com/atlas/assets/wbtc/): The on-chain wrapper depends on named custodial and administrative parties. It is not equivalent to native, self-custodied Bitcoin.
- [BUIDL control profile](https://riadefi.com/atlas/assets/buidl/): Yes. The tokenized fund is permissioned and administered; transfer and holder controls are features of the legal product.
- [Ethereum chain profile](https://riadefi.com/atlas/chains/ethereum/): None — permissionless proposer set
- [Arbitrum One chain profile](https://riadefi.com/atlas/chains/arbitrum/): Centralised — >99% of transactions through a single sequencer
- [Base chain profile](https://riadefi.com/atlas/chains/base/): Centralised — operated by Coinbase, a single regulated US entity
- [Solana chain profile](https://riadefi.com/atlas/chains/solana/): Leader schedule across the validator set — no single operator
