Institutional investors moving sizeable positions have always faced a difficult choice: execute on a public exchange and accept slippage costs that can reach multiple percentage points, or go off-exchange and navigate a fragmented network of brokers with inconsistent pricing and opaque fees. OFFX Block Trades solves this problem by aggregating deep liquidity from multiple providers into a single, simple workflow.

Block Trades are purpose-built for large-volume OTC execution. Whether you're moving millions in tokens or equity, the platform uses an RFQ (request for quote) engine to simultaneously query multiple liquidity providers, returning the best executable prices in real time. This means no slippage — you get the exact price you see, executed as a single atomic transaction. For institutional players, this is a material difference. A five-percent slippage on a hundred-million-dollar position costs five million dollars. Block Trades eliminate that drag entirely.

The infrastructure is designed for institutional workflows. Once onboarded to OFFX and Blockfort custody, you have access to best-in-class liquidity through a single interface. There's no shopping around for brokers or negotiating with multiple counterparties. The platform handles all of that behind the scenes. You get aggregated liquidity, transparent pricing, and the ability to control exactly who sees your order and when. Deals can be public, private, or fully anonymous depending on your preference. The order visibility remains yours to control.

Settlement happens through Blockfort-controlled escrow, which means the entire transaction is atomic and trustless. You submit an RFQ, receive quotes, accept the best one, deposit your tokens or assets, and Blockfort validates everything and executes the settlement. The buyer's assets flow to you at the exact moment your assets flow to them — no intermediaries, no settlement delays, no counterparty risk.

What makes this unique is that every piece is integrated. Liquidity aggregation, order management, execution, escrow, and settlement all happen in a single workflow. There's no jumping between systems or managing multiple relationships. For sellers, this means clean execution without the friction of traditional OTC. For buyers, it means access to a marketplace of institutional-quality liquidity without having to build relationships with dozens of brokers. And for both sides, it means transparent pricing and minimal execution cost.

OFFX Block Trades represent a fundamental shift in how institutional investors access liquidity for large positions. One onboarding. Best-in-class pricing. Trustless settlement. That's the future of private market execution.

OFFX Block Trades: Deep Liquidity for Large-Volume OTC Execution

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.
