Royalties that cannot be bypassed. Transfer constraints that cannot be circumvented. Dynamic metadata that evolves autonomously. This is not another ERC-721 wrapper — this is tokenization reimagined from the protocol up.
Policy contracts, automatic royalties, and 7 sale price verification models — all enforced at the protocol layer
Token and NFT creation is native to the ATSHI protocol — not a smart contract standard. The transaction structure natively supports token minting, transfers, and NFT creation at the ledger level. Unlike ERC-20/ERC-721, which require deploying a contract for every token, ATSHI handles basic token operations as built-in ledger operations. Policy contracts add programmable rules on top of this native foundation.
Protocol-NativeEvery token collection is governed by a policy smart contract that defines its rules. Transfer constraints, royalty percentages, whitelist/blacklist logic, time locks, and geographic restrictions are all encoded once and enforced forever. No marketplace cooperation required.
GovernanceRoyalties are computed and collected at the protocol level during every transfer. There is no way to bypass them — no wrapping tricks, no private sales, no marketplace opt-outs. Creators earn on every single transaction, guaranteed.
CreatorsWhitelist (only approved wallets), blacklist (block specific addresses), time lock (tokens frozen until a date), geographic restriction (transfer only within permitted jurisdictions). All enforced cryptographically, not by a centralized gatekeeper.
ComplianceToken Policy Engine
Tokens can change their own metadata based on on-chain events, time, or external triggers. An NFT that evolves when its owner stakes, a token that unlocks features after a holding period, a collectible that ages visually — all autonomous, all on-chain.
DynamicSale prices can be encrypted with FHE so that the protocol verifies royalty computation without revealing the actual price. Seven distinct price verification models cover auctions, fixed sales, offers, bundles, and more.
PrivacyTokens carry their own trading logic. No need for external marketplaces — listing, bidding, and settlement happen through the token's own smart contract. The marketplace is the token.
IndependenceOn other chains, token rules are suggestions. On ATSHI, they are laws of physics.
Creator royalties are enforced at the protocol level — not by marketplace goodwill. Every transfer, every sale, every swap triggers automatic royalty collection. No wrapping exploits, no private deal loopholes.
CreatorsTransfer constraints are baked into the token itself. Whitelist-only transfers for security tokens, geographic restrictions for regulatory compliance, time locks for vesting — all enforced without a centralized authority.
ComplianceTokens are alive. NFTs that evolve based on holder behavior, real-world assets that update their valuation on-chain, collectibles that age and transform — metadata changes are autonomous and verifiable.
InnovationNo dependency on OpenSea, Blur, or any external marketplace. The token IS the marketplace. Listing, bidding, and settlement all happen through the token's policy contract. Zero platform risk.
IndependenceSale prices can be encrypted so that competitors never see your deal terms. The protocol still verifies royalties are correct through homomorphic computation on ciphertext. Privacy and enforcement coexist.
PrivacyReal-world assets — real estate, art, commodities, securities — can be tokenized with compliance constraints built in. Transfer restrictions, accredited investor checks, and jurisdictional rules are protocol-native.
Real WorldOther chains rely on marketplace cooperation for rules. ATSHI enforces them at the protocol.
