Chaintope Inc. (Headquarters: Iizuka City, Fukuoka Prefecture; CEO: Hideki Shoda; hereinafter "the Company") has today released "Tapylet," a Chrome extension wallet for its proprietary public blockchain "Tapyrus."
This release is exclusively for the Tapyrus Testnet and is intended for use by developers and companies for testing and verification purposes. Moving forward, the Company plans to enable support for production environments, such as through its "Tapyrus API," aiming for use in actual commercial services.
■ About Tapylet
Tapylet is a browser wallet extension compatible with the Tapyrus blockchain. Similar to "MetaMask" in the Ethereum ecosystem, it allows users to easily access the Tapyrus network from their browser to manage digital assets and issue tokens. It adopts a non-custodial system where private keys are stored only on the user's device, balancing security and convenience.
Key Features:
- Native Currency (TPC) Management: Balance checks, sending/receiving, and address sharing via QR codes.
- Colored Coin (Token) Support: Sending, receiving, and burning of Reissuable Tokens, Non-reissuable Tokens, and NFTs.
- Token Issuance: Supports three token types and allows setting metadata (name, symbol, description, icon, etc.) in compliance with the TIP20 standard. Supports outputting registration information for the Token Registry.
- Security: Backup via a 12-word recovery phrase, password encryption protection, and local storage of private keys.
■ TIP20 Standard and Token Registry
Tapylet supports the TIP20 (Tapyrus Improvement Proposal 20) standard developed by the Company. TIP20 is a standard specification for linking metadata to Tapyrus colored coin tokens, utilizing Pay to Contract (P2C) technology to make commitments to metadata during token issuance. This enables consistent display of token information across wallets and applications.
Furthermore, metadata of issued tokens can be shared across the entire ecosystem by registering it in the open Token Registry (https://github.com/chaintope/tapyrus-token-registry).
■ Future Outlook
- Production Environment Support: While currently for testnet only, a version capable of connecting to production environments like the "Tapyrus API" is planned. This will allow end-users to manage tokens and perform authentication through Tapylet in actual services built on Tapyrus.
- Sign in with Tapyrus: As a future feature, "Sign in with Tapyrus" will be implemented. This is similar to the "Sign-In with Ethereum (SIWE)" concept, using the wallet's private key to authenticate with web services. Since it requires no password and uses the blockchain address as an identity, use cases such as logging into dApps, linking with identity verification (JPKI/My Number Card) or W3C Verifiable Credentials, and access management for corporate systems are expected.
■ Use Cases Opened by Tapylet
The release of Tapylet makes it easier to develop and verify use cases utilizing the Tapyrus blockchain, such as traceability and proof of origin for agricultural or industrial products, allowing consumers to verify authenticity directly from their browser.
