01 · The Brief

In conventional crypto fundraising, early investors and team members typically receive tokens subject to vesting schedules that restrict transfer and liquidity for long periods.

That illiquidity is costly for holders who want optionality, and it limits how new participants can access these allocations on clear, verifiable terms. SecondSwap addresses that gap by making vesting positions tradable while preserving clarity about what is being bought and when it unlocks. Supporting multiple ecosystems was essential because token issuance, liquidity, and user behavior are not confined to a single chain; the product therefore needed cross-chain depth (contracts, apps, and analytics), not a single-stack prototype.

Business Objectives

SecondSwap enables trading locked and vesting token allocations before unlock, giving sellers liquidity and buyers discounted, transparent on-chain vesting. The build covered Avalanche, Ethereum, and Solana, from smart contracts to user products and Dune dashboards.

01
Build Smart Contracts for Tradable Vesting
Design and deploy step-vesting and marketplace contracts on EVM (Solidity) and SVM (Anchor/Rust) that enable listing, purchasing, transferring, and claiming of vesting positions.
02
Launch a Multi-chain Marketplace
Deliver a production marketplace where users can discover, list, and purchase vesting allocations across Avalanche, Ethereum, and Solana with a unified experience.
03
Achieve Foundation Grant Milestones
Delivered capabilities top unlock milestones for 2–3 major blockchain foundations, including launches on Avalanche, Solana, and Ethereum by hitting user and transaction growth targets, and measurable protocol adoption.
04
Establish Analytics & Reporting
Build public-facing analytics (Dune dashboard) and internal operational dashboards (Metabase) to track TVL, transactions, connected wallets, and chain-level metrics.

How we brought it to life.

Secondary Locked Token Marketplace

Secondary marketplace & marketplace contract — We built a secondary marketplace backed by a marketplace smart contract so holders can list tokens and list vesting positions for sale, turning long-dated schedules into tradeable positions. Vesting contracts can be split into multiple tranches—buyers purchase pieces of a position and claim those tranches on their own schedule; sellers can exit early, take profit, or re-list as the market moves. The experience is multi-chain, with support on Solana, Ethereum, and Avalanche.

05 · Results

Hoasen worked with secondswap over more than one year through the launch of the platform on 3 different networks.

Our work included developing the smart contract and refactoring and launching a second version of the smart contract with improved capabilities

5,000 Users Reached a key milestone of $6M peak TVL The platform hit about six million dollars in total value locked at peak, across the chains it supports.

Foundation grant milestones achieved Deliverables for two to three foundation programs shipped on schedule—EVM go-lives, user milestones, and transaction targets included.

Significant investment secured A substantive round came together on the strength of the shipped product and clear traction in the market.

SecondSwap proved that locked vesting positions can trade as a liquid asset class. The protocol now runs across three major ecosystems, with a growing user base and an active marketplace—set up for the next phase of growth.
