Custody, Escrow & Block Trades — The Full OFFX OTC Stack

OFFX and Blockfort bring execution, settlement, and custody together in one integrated workflow — built for institutional OTC and secondary markets.

One Platform. Three Products. Zero Gaps.

Most OTC desks offer execution. Some offer custody. A few offer escrow. Nobody combines all three into a single workflow — until now.

Through our joint venture with Blockfort AG, OFFX has built an integrated stack that covers the full lifecycle of an OTC or secondary transaction: from price discovery to custody to final settlement. One onboarding. One counterparty. No stitching together three different providers.

OFFX Block Trades

Large spot trades that are too big for exchange order books without moving the market. OFFX aggregates liquidity across top-tier providers through a competitive RFQ process — sellers get institutional pricing without slippage, and liquidity providers get access to verified, off-exchange deal flow.

Block Trades

Deep Liquidity, Executed OFFXchange

Submit a request for quote specifying asset, size, and timing. Multiple liquidity providers compete on price. Settlement is handled sequentially through Blockfort — tokens release first, then USDC follows upon confirmation. Neither side takes unnecessary risk.

No slippage

Negotiated pricing via competitive RFQs, not order books

Full anonymity

Liquidity providers never see the seller's identity

Aggregated liquidity

Best pricing across multiple providers, no conflict of interest

Single onboarding

One account unlocks all counterparties and venues

OFFX Escrow

OTC trades only work when both sides can trust the settlement. OFFX Escrow removes counterparty risk entirely by holding assets in Blockfort-controlled custody until all conditions are met — then releasing them atomically. Both sides settle together, every time.

Escrow

Secure Settlement for Any Deal Structure

Whether it's a straightforward spot OTC deal, a pre-launch allocation with TGE conditions, or a forward agreement with vesting logic — OFFX Escrow handles it. Assets are deposited, Blockfort validates balances and conditions, and release happens either instantly or based on pre-defined triggers.

Atomic settlement

Tokens and funds release together — no partial fills, no trust required

Conditional logic

TGE triggers, vesting schedules, time-locks, and collateral structures

Multi-structure

Spot, forwards, token swaps, pre-launch, and collateralized deals

Swiss-regulated

Blockfort as independent third-party enforces every settlement

OFFX Custody

The backbone of it all. OFFX Custody isn't cold storage you forget about — it's custody that connects directly into the OTC ecosystem. Assets held in Blockfort custody can be traded, escrowed, staked, or structured for secondary sales without ever leaving the institutional-grade environment.

Custody

Institutional-Grade, Built for Trading

Powered by Blockfort's Swiss-regulated infrastructure and built on Fireblocks MPC with segregated client vaults. Your custody account plugs straight into OFFX's OTC and RFQ flows — one onboarding gives you access to execution, escrow, and settlement in a single stack.

Custody, Escrow & Block Trades — The Full OFFX OTC Stack

In the locked-token secondary market, every trade has been all-or-nothing: you sell the entire vesting schedule, or nothing at all. OFFX Custody changes that. With custom vesting schedules, sellers and buyers can now agree on exactly which vesting events change hands — unlocking flexibility that never existed before.

How It Works

On OFFX, sellers choose exactly which vesting events to sell. Instead of listing an entire 24-month schedule, you can select just the first 12 months — or any combination that fits your needs.

1

Create a deal on offx.tech

Start a new deal and select the asset you want to sell.

2

Choose your vesting schedule

Select the vesting allocation that applies — the platform displays every event in your schedule.

3

Customize your events

Pick exactly which vesting events to include. Sell the first 12 months, skip the cliff, or any combination — you decide.

4

Settle with the buyer

Once matched, OFFX Custody handles delivery automatically — guaranteed settlement, no manual transfers.

Requires an OFFX Custody account, powered by Blockfort.

Example: pump.fun Investor Allocation

Scenario

When the buyer wants a discount the seller won't accept

An existing investor holds a 3-year pump.fun vesting schedule. A buyer bids 60% discount on the full schedule — implying ~$800M FDV. But the seller is only willing to sell at a 25% discount, closer to ~$1.5bn FDV.

With traditional OTC, this deal is dead. The price gap is too wide for a full-schedule trade.

Buyer's bid
60% discount
Full 3-year schedule
Implies ~$800M FDV
Seller's ask
25% discount
Only willing at ~$1.5bn FDV
Won't sell everything that cheap

With custom vesting on OFFX, they meet in the middle. The seller lists only the cliff unlock + first 12 months of monthly vesting. The buyer gets shorter exposure at a price they accept — and the seller keeps the remaining upside.

Cliff — Jul 2026 Selling: 13 events Keeping: 24 events
Deal closes at 25% discount — both sides win ~$1.5bn FDV

Every locked-token deal used to require the same compromise: sell everything, or sell nothing. Custom vesting schedules remove that constraint entirely. Sellers access liquidity without giving up their long-term position. Buyers get precisely the exposure they want. And OFFX Custody guarantees every event settles — no counterparty risk, no manual transfers, no trust required.

Sell what you want. Buy what you need.
