Autonomous agents with enforceable limits
Give an agent a time-limited capability defining exactly which tools, data, budgets, counterparties, and actions it may use.

A safer foundation for digital agency.
Identity, assets, computation, and AI share the same language of scoped authority and verifiable evidence.
Private, reusable digital identity
Prove age, membership, professional status, authorization, uniqueness, or non-revocation while revealing only what the transaction requires.
Prove the policy. Keep the record.Native issued assets
Represent EUR, USD, community currencies, loyalty value, regulated instruments, and other issued assets as first-class objects with explicit issuer and policy semantics.
Proof-carrying smart contracts
Explicit, resource-safe objects execute in parallel while effects remain atomically composable within one global state.
Validity is a property of the transitionVerifiable AI and computation
Bind an output to an exact model, runtime, input commitment, random seed, data authorization, and execution method.

The core path requires no classical elliptic-curve primitive to authorize state, finalize consensus, or verify execution.
Stablecoins belong in the validity model
EUR, USD, and any issued asset—native from first principles.
Actum is designed so an issued euro, dollar, bond, fund share, commodity claim, ticket, or real-world asset does not need a separate token contract to become legible to the network. Asset identity, supply authority, policy, and evidence are protocol concepts that wallets, validators, applications, and proofs can interpret consistently.
Wallets and integrators must rediscover decimals, controllers, upgrade keys, compliance rules, reserve claims, and transfer behavior contract by contract.
The protocol binds the asset definition, issuer and controller authority, units, supply rules, policy commitments, lifecycle events, and proof-bearing receipts.
Issue and redeem
Canonical mint, burn, redemption, and supply events are authorized explicitly and remain independently auditable.
Enforce bounded control
Issuer, reserve operator, compliance officer, and emergency controller can hold separate attenuated capabilities instead of one omnipotent admin key.
Compose private policy
A transfer can prove required attributes—such as adulthood, residency eligibility, or sanctions-policy satisfaction—without publishing the holder’s identity or exact attributes.
Carry reserve evidence
Reserve attestations, proof-of-funds credentials, liabilities commitments, and auditor receipts can be bound to issuance policy and verified as evidence rather than trusted prose.
Work in every wallet
ACT, EUR-denominated, USD-denominated, and other native assets use one discoverable Coin Cell and proof model; wallets do not need a new execution engine for each issuer.
Remain issuer-configurable
The protocol supplies primitives, not one mandatory business policy. Operators choose governance, redemption, disclosure, jurisdiction, limits, fees, and permitted proof profiles.
One protocol-native lifecycle

Compliance is a profile, not a global switch
Jurisdiction-aware rules can change without changing the asset.
Issuers and operators publish versioned profiles for the markets they serve—such as the EU, US, Tanzania, or Kenya. Each profile names its accepted credentials, screening sources, freshness limits, transfer fields, and review authority. At admission time, the chain selects the applicable, non-expired profile deterministically; conflicting or ambiguous profiles go to an identified manual-review process, and unresolved cases fail closed.
Reference application / Amber
Amber is a private imageboard built on Actum.
Amber demonstrates pseudonymous identity, private membership, scoped moderation authority, proof-bound publishing, and portable reputation without turning the application operator into the source of truth.
