Legacy Practice

Avoid wallets and exchanges for stablecoin treasury

Wiring millions in USDC/USDT through wallets and spreadsheets means you lack a treasury system and face risks.

Fragmented custody

Hardware wallets, CEX accounts, multisigs, and spreadsheets don’t talk to each other. There’s no single view of balances, risk, or approvals.

Fragmented custody

Hardware wallets, CEX accounts, multisigs, and spreadsheets don’t talk to each other. There’s no single view of balances, risk, or approvals.

Key-person and key-device risk

One “crypto person” holds the keys. If they’re hacked, leave, or make a mistake, the company’s runway can disappear in a single transaction.

Manual, after-the-fact controls

Sanctions screening, taint analysis, and policy checks happen in someone’s head or in a separate tool—after the transaction is queued, not before it’s signed.

No audit trail a CFO can defend

Approvals are buried in Telegram, Slack, or email threads. There’s no clean story for auditors, boards, or regulators.

Architecture

The control plane for your stablecoin treasury

Stablerail is a self-custodial treasury platform above your wallets. You keep keys in MPC-secured vaults, with policies and an AI copilot enforcing rules.

Self-custodial MPC vaults

Stablecoin balances are held in MPC-secured vaults, not in our custody. Stablerail never has unilateral signing power.

AI copilot for checks, not bets

The copilot assesses transactions against your policies and explains risks clearly for human decisions.

Process

How Stablerail fits into your day-to-day

Step 01

Set your guardrails

Define who can move how much, to whom, on which rails, and when. Encode approvals, limits, whitelists, and velocity rules as reusable policies.

Move funds into governed vaults

Connect your existing wallets and rails, and move stablecoin balances into MPC-secured vaults governed by Stablerail policies. See a consolidated view of balances, exposures, and pending approvals in one console.

Execute with the copilot watching

When a transaction is created, the AI copilot runs sanctions and taint checks, policy checks, anomaly detection, and counterparty checks—then explains any issues before a human signs.

Nothing moves without a human signature. The AI can only block, flag, and explain — never spend.

Playbooks for recurring flows like payroll, vendor payouts, and inter-entity transfers

Real-time view of stablecoin positions, pending approvals, and risk exposure

Notifications and approvals surfaced in Slack/Teams with links back to Stablerail

Compliance & Risk

Bake compliance into the transaction flow instead of bolting it on.

Sanctions and watchlist checks for counterparties

On-chain taint analysis to spot links to hacks, mixers, or high-risk entities

Jurisdiction-aware rules by entity, country, or business unit

Clear explanations when a transaction is blocked or downgraded

Security model

Agents verify, humans sign, keys remain distributed.

We design for adversarial environments: crypto markets, social engineering, SIM swaps, and insider risk.

Non-custodial by design

Stablecoins are held in MPC-secured vaults. Keys are split across multiple parties, with configurable signing thresholds. Stablerail never has unilateral control over your funds.

AI in the verification layer only

The copilot can read policies, transaction context, and on-chain data. It cannot hold keys, initiate transfers, or sign. Its only role is to block, flag, and explain.

Operational hardening

SSO and SCIM, enforced MFA, hardware keys for signers, and strict least-privilege access. Environments are separated across sandbox, staging, and production.
