โ“ Frequently Asked Questions

OpenFund is a pseudonymous, no-KYC crowdfunding platform built on Solana. Anyone with a Solana wallet can create a fundraiser or donate to a campaign โ€” no identity verification, no bank accounts, no gatekeepers. Payments are made directly in USDC on-chain.

A

Powered by Pump.fun Tokenized Agents

OpenFund is one of the first platforms to integrate Pump.fun's Tokenized Agents โ€” a new on-chain primitive that lets applications collect revenue and automatically reinvest a portion into token buybacks. This creates a sustainable flywheel where platform usage directly benefits the community.

How It Works

A smart contract sits on top of the Pump bonding curve. When donations flow through the agent, a configured percentage is automatically used for buybacks โ€” no manual intervention, no trust assumptions.

Why It Matters

Traditional platforms pocket their fees. With Tokenized Agents, revenue is recycled back into the token, creating organic demand that grows with platform adoption.

Dual Payment Paths

OpenFund supports both x402 direct USDC payments and the new Agent Token path. Users choose which method they prefer โ€” nothing is forced.

Fully On-Chain

Buyback logic is enforced by Solana smart contracts, not off-chain promises. Every transaction is verifiable on-chain via invoice validation.
