§ THE STACK

Four surfaces. One binding chain.

Off-chain, the proprietary judgment core: the PCE compiles regulation and mandate into attested executable policy, and the AIA turns every decision into a co-signed receipt. On-chain, the open substrate: OMA enforces before settlement, STN matches and settles confidentially. A single policy-commit hash threads all four, so the rule that was authored is provably the rule that executed.

From mandate to evidence.

Compile → attest → enforce → settle → record. The execution plane is open source and standards-based on purpose; the judgment plane (and the decision record it produces) is the product.

Guarantees, not aspirations.

PROP · 01
Compiled policy
Glass-box AI extraction under counsel review turns prose into typed rules, with every predicate pinned to the source clause and the reviewer who approved it.
PROP · 02
Verdicts with reasons
Admit, reject, or escalate in about a millisecond, each verdict carrying the rule IDs and computed reasons that decided it.
PROP · 03
Attested receipts
Human-readable clear-signing receipts co-signed by an independent quorum. Any supervisor can verify them without trusting OnTrade.
PROP · 04
Atomic settlement
Multi-leg, cross-asset batches finalize together or revert together. No settlement-failure tail, no counterparty credit exposure post-match.
PROP · 05
Confidential by encryption
FHE matching and confidential transfers seal positions cryptographically, not contractually. Positions never leak; proofs still verify.
PROP · 06
Evidence by construction
Audit packs assemble themselves from execution, replayable by depositary, auditor, or regulator, each to the extent they are entitled.

What the engine actually does.

Policy compilation
Regulatory corpora (MiCA, MiFID II, AIFMD/UCITS evidence duties) and private mandates compiled into versioned, machine-executable rule bundles.
CAPABILITY · 01
Pre-trade verification
Every intent checked against the full compiled rulebook before settlement: admit, reject, or escalate, with clause-level reasons.
CAPABILITY · 02
Clear-signing attestation
ERC-7730 descriptors pin the policy commit; an ERC-8176 multi-signer quorum signs every approval.
CAPABILITY · 03
Modular smart accounts
ERC-7579 Validator / Executor / Hook modules on a per-mandate account, inside the institution's own trust boundary.
CAPABILITY · 04
Permissioned assets
ERC-3643 (T-REX) identity-bound tokens; transfer eligibility re-checked on every leg, on both sides.
CAPABILITY · 05
MPC signing
Threshold signatures map PM, risk, and treasury onto a quorum policy. No single private key exists to compromise.
CAPABILITY · 06
Confidential settlement
TFHE-sealed amounts and counterparties via confidential transfer standards (ERC-7984); selective disclosure per authorized viewer.
CAPABILITY · 07
Replayable audit packs
Dated audit queries answered from evidence bundles. Same bundle + same intent = same verdict, deterministically, forever.
CAPABILITY · 08

Measured, not promised.

Baselines from the proof-of-concept series, spanning the full stack: policy gate, atomic execution, and the evidence pipeline, end to end.
