PayFi.Fun describes itself as a full-stack, aggregated infrastructure platform for the Bitcoin ecosystem, with native integration across BTC, ETH, Solana and ICP. The project says it uses ICP’s chain-fusion technology to connect payments with financial services, cut transaction costs, improve capital efficiency and link users to ICP-based DeFi, NFT and Web3 applications.
Timeline presented by the project
According to the project materials, ICP completed native support for Bitcoin integration in 2022.
In Q2 and Q3 of 2022, the integration plan was disclosed, stating that ICP would connect directly with Bitcoin through Chain Key and Threshold ECDSA. On Dec. 6, 2022, the DFINITY Foundation formally announced that integration between the ICP mainnet and the Bitcoin network had been completed. From that point, canister smart contracts on ICP were able to natively hold, send and receive bitcoin without using a bridge or a third-party custodian.
How the technology is described
The project says the core of that setup is Threshold ECDSA, together with the later introduction of the Threshold Schnorr signature protocol. In its description, canisters can create Bitcoin addresses, sign transactions and broadcast them to the Bitcoin network without exposing private keys. The project presents this as native BTC support rather than support limited to wrapped assets such as ckBTC.
Launch schedule and product functions
Project materials say PayFi.Fun, which it calls the first full-stack aggregated infrastructure platform for the Bitcoin ecosystem, started development in December 2022 on ICP’s underlying technology and launched a public beta on Aug. 1, 2025.
The beta version is described as delivering three technical breakthroughs for the BTC ecosystem: speed below one second, fees below $0.01 and container smart contracts. The platform also lists five core functions:
- one-click token issuance
- one-click mapping
- adding and removing liquidity
- a decentralized exchange
- a decentralized wallet
Under the project roadmap, the formal launch is set for Aug. 1, 2026. It says the ecosystem will then expand into an Elephant multi-chain identity wallet, crypto social products, crypto conferences, cross-border e-commerce, cross-border payments, blockchain games and prediction markets.
Cross-chain approach and platform claims
In its cross-chain section, PayFi.Fun says users can map Bitcoin assets to ICP with one click to access faster transaction speeds. The project lists several features:
- second-level transaction confirmation based on ICP chain-fusion technology
- support for mapping SRC20 and BRC20 tokens into the ICP ecosystem
- trade-path optimization through an AMM mechanism
- an effort to connect payments and financial services
Advantages and use cases listed by the project
The platform groups its advantages into transaction speed, cost efficiency, ecosystem interoperability and security. It says users can move from Bitcoin’s minute-level confirmation experience to second-level trading on ICP, lower transaction costs and improve capital efficiency, while also accessing ICP’s DeFi, NFT and Web3 ecosystem. On security, the project says it is protected by an advanced security system and global certifications.
For use cases, PayFi.Fun says users can get faster and cheaper payments on ICP, build BTC-supported applications with smart contracts and move assets across different blockchains while adjusting allocation.
Ownership and issuance features
The project also lists features tied to ownership, transparency and creator royalties. In its description, users retain full ownership of digital assets and the platform cannot reclaim them at will. Each action is recorded on-chain and can be checked publicly. Artists and developers can receive royalties automatically and on an ongoing basis.
For issuance-related functions, the platform says it supports single-transaction minting, minting the full token supply at once, flexible distribution strategies, presales and airdrops. On fair launch mechanics, it says there is no pre-mining or pre-allocation, rules are fully transparent and the community can participate on equal terms.
TOKEN2049 appearance in Singapore
The project materials say PayFi.Fun was invited to attend and exhibit at TOKEN2049 in Singapore in October 2026. It says the team introduced the project’s original purpose, vision and main functions to attendees interested in the Bitcoin ecosystem, and that the appearance drew praise and media coverage.
