01 — Mechanism How Meridian executes

An autonomous agent for treasury, not a black box.

Meridian is non-custodial. Funds remain in your multisig at all times. The protocol executes signed instructions deterministically against TON and USD rails — no off-chain trust assumptions, no opaque routing.

01

Define

Express treasury policy in TypeScript or natural language. "Pay vendor 5,000 USDT every Friday." "Convert TON above 100k threshold to USDT." Rules compile to verifiable on-chain commitments before execution.

02

Execute

Meridian runs as a non-custodial agent on TON. Each transaction is co-signed by your organization's multisig and the protocol's policy verifier. No instruction executes without cryptographic authorization.

03

Verify

Every action is recorded on TON with a permanent audit trail. Reconciliation is automatic across USD and TON ledgers. SOC 2 reports and on-chain proofs are issued continuously, not annually.

02 — Policy The contract you sign once

Treasury rules, expressed once. Enforced forever.

Policies are deterministic. They cannot be silently modified, rerouted, or front-run. Changes require a multisig quorum and a 24-hour timelock, surfaced on-chain before execution.

03 — Console Live treasury operations

A command surface for the people accountable for the money.

CFOs, controllers, and treasury operators see balances, pending instructions, and on-chain proofs in one console. Engineers integrate via SDK. Auditors get continuous, signed reports.

04 — Custody & compliance Built to pass institutional review

Non-custodial by architecture. Audited by independent firms.

Meridian is built for organizations that have to defend every dollar in front of a board, an auditor, or a regulator. The protocol holds no principal, takes no spread, and produces a continuous, verifiable audit trail by default.

Always verify the contract address on a trusted explorer before any transaction. Meridian will never DM you. Phishing attempts impersonating the protocol are tracked at security.meridian.fi.

07 — Community airdrop 2% of supply · 20,000,000 MRDN

A piece of the network for the community that holds it up.

Meridian is reserving 2% of total supply — 20,000,000 MRDN — for an early-community airdrop. Eligibility is determined by on-chain activity: TON power users, treasury operators, forum contributors, and design partners. Submit your TON wallet below to be considered. Snapshot date will be published fourteen days in advance.

Submit TON wallet PRE-SNAPSHOT

By submitting, you confirm you control this wallet. One submission per person. Eligibility is final at snapshot. Submitting does not guarantee an allocation.

The work of the treasury
shouldn't take a treasury team.

Meridian is opening private access to a small set of design partners — funds, market makers, payroll providers, and on-chain businesses with predictable cashflows.
