Sign (SIGN) is an identity and signature protocol built on the Ethereum blockchain, designed to provide secure and verifiable digital signatures for Web3 applications.

Key takeaways

• Sign (SIGN) is a digital identity and signature protocol operating on the Ethereum network.
• It utilizes the Keccak-256 hash algorithm for cryptographic security.
• The protocol aims to provide verifiable and secure digital signatures for decentralized applications (dApps).
• SIGN has a maximum supply of 10,000,000,000 tokens.
• It gained significant attention as a key discussion topic at the Consensus Hong Kong conference in February 2026.

What is Sign (SIGN)? Key Specifications & Tokenomics

Sign (SIGN) is a protocol that enables secure, on-chain digital signatures and identity verification, leveraging Ethereum's security and smart contract capabilities.

Who created Sign (SIGN)?

The Sign protocol was developed by a team focused on digital identity solutions within the Web3 space. While specific founder details are often decentralized in such projects, the protocol's development is managed by its core contributors and community. The project gained a major platform at the Consensus Hong Kong conference in February 2026, where it was highlighted as a significant innovation in the identity and signature sector. This spotlight helped establish SIGN as a serious contender in the blockchain-based digital identity landscape, attracting developer and user attention to its potential applications.

How does Sign (SIGN) work?

The Sign protocol functions as a layer on top of the Ethereum blockchain. It uses smart contracts to manage the creation, verification, and revocation of digital signatures. When a user creates a signature for a document or transaction, the protocol generates a unique cryptographic hash using the Keccak-256 algorithm. This hash, along with the signer's verified identity metadata, is then permanently recorded on the blockchain. This process provides an immutable and publicly verifiable proof of who signed what and when. By being EVM-compatible, the protocol can be easily integrated into a wide range of existing and future decentralized applications (dApps) on Ethereum and its Layer 2 networks like Base, which host its primary smart contracts.

What makes Sign (SIGN) unique and valuable?

Sign's primary value proposition lies in bringing legally significant and cryptographically secure digital signatures to the blockchain. Unlike traditional digital signatures, SIGN signatures are tamper-proof and independently verifiable by anyone on the network, eliminating the need for trusted third-party validators. Its use of the robust Keccak-256 hash algorithm, also used by Ethereum itself, ensures a high level of cryptographic security. Furthermore, its design for the EVM ecosystem means it can seamlessly serve the vast universe of Ethereum-based dApps, from DeFi agreements to NFT ownership transfers. The protocol's feature at a major industry conference like Consensus underscores its perceived technical merit and real-world utility potential.

What is Sign (SIGN) used for?

The SIGN token and protocol are designed for several key use cases within Web3:

• Smart Contract Execution: SIGN can be used to authorize actions within dApps, providing a clear, on-chain record of consent.
• Document Signing: Creating verifiable signatures for legal documents, contracts, or certificates directly on the blockchain.
• Identity Verification: Serving as a component in decentralized identity (DID) solutions, where a signature can attest to specific identity attributes.
• Governance: SIGN token holders may participate in the decentralized governance of the protocol, voting on upgrades and parameter changes.
• Transaction Signing: Providing an extra layer of attestation for significant blockchain transactions.

How Is the Sign (SIGN) ecosystem developing?

The Sign ecosystem is evolving through integration and partnership. Its EVM-compatibility is a major growth driver, encouraging dApp developers on Ethereum and Layer 2s like Base to incorporate its signature functionality. The attention from the Consensus conference likely accelerated developer interest and potential enterprise adoption. Ecosystem development focuses on building tools, SDKs, and wallet integrations that make it easy for users to create and manage their Sign-based signatures. The long-term vision is to become a standard infrastructure layer for trusted digital agreements across the decentralized web.

How to mine Sign (SIGN)?

SIGN is not a mineable token in the traditional Proof-of-Work sense. It is an ERC-20 utility token issued on the Ethereum blockchain. The tokens were likely distributed through an initial coin offering (ICO), token sale, or other allocation mechanisms defined by the project's founders. All SIGN tokens in existence were created at genesis, up to its maximum supply cap. Therefore, new SIGN tokens cannot be created through mining. The network security for the Sign protocol itself relies on the underlying Ethereum blockchain's Proof-of-Stake consensus mechanism.

How to keep your SIGN Coin safe?

Securing your SIGN tokens is crucial since they are digital assets on the Ethereum blockchain.

• Use a Hardware Wallet: For significant holdings, store your SIGN in a hardware wallet like Ledger or Trezor. These devices keep your private keys offline, providing the highest security against online threats.
• Secure Software Wallets: For smaller, more frequently used amounts, consider reputable, non-custodial software wallets (e.g., MetaMask, Trust Wallet). Always download wallets from official sources.
• Guard Your Private Keys and Seed Phrases: Never share your private keys or 12/24-word recovery seed phrase with anyone. This information gives full control over your assets.
• Beware of Phishing: Be cautious of fake websites, emails, or social media messages pretending to be from wallet providers or exchanges. Always double-check URLs.
• Smart Contract Audits: Before interacting with any dApp using SIGN, verify if the project's smart contracts have been audited by reputable security firms.

How to buy SIGN Coin?

SIGN is a cryptocurrency that can be traded on several exchanges. For a secure and liquid trading experience, using a major platform like BTCC is recommended.

1. Register a BTCC Account: Sign up using your email or mobile number and complete the KYC verification to unlock more features and benefits of the platform.
2. Deposit Funds: Deposit fiat currency (via bank transfer, card, or third-party payment) or transfer USDT from an external wallet into your BTCC account. You can follow this guide on how to buy USDT.
3. Start Trading: Go to the trading page and search for the spot trading pair SIGN/USDT or the perpetual contract SIGNUSDT.
4. Place an Order: Enter the amount of SIGN you wish to purchase and submit the order. For contract trading, you can also choose to go short (sell) and adjust the leverage multiplier according to your strategy and risk tolerance.
5. Confirm Your Purchase: For spot purchases, check your personal account to see if the coins have arrived. For contract trades, check the trading page to see if your order was filled successfully.
