Key Takeaways

Sign allows users to create and verify digital attestations across multiple blockchains. 

It uses encryption and zero-knowledge proofs to ensure that claims about identity, ownership, or agreements are secure and easily verifiable across different networks.

Users can prove ownership, identity, or eligibility without revealing unnecessary personal information.

TokenTable gives projects a range of options for managing token distributions, such as airdrops, vesting schedules, or token unlocks.

Introduction

In today’s digital world, proving who you are online matters more than ever. The Sign project was built to make it easier for people and businesses to verify identities and share credentials securely, using blockchain technology. It also helps projects distribute tokens in a smarter and more flexible way.

What Is the Sign Project?

The Sign project addresses the need for secure, verifiable, and accessible credentials in the digital world. Combining blockchain technology, smart contracts, and privacy measures, Sign offers a decentralized approach to verifying identity, ownership, and contracts across multiple blockchain networks.

How Does Sign Work?

The Sign ecosystem is made up of four key products:

Sign Protocol: Facilitates the creation and verification of attestations across multiple chains.

TokenTable: A platform for distributing tokens via methods like airdrops, vesting, and unlock schedules.

EthSign: A decentralized application (DApp) for executing digital agreements on-chain.

SignPass: A system for on-chain identity registration and verification. It helps users prove their identity online.

Sign Protocol

Sign Protocol is like a digital notary. It lets users issue and verify claims about things like identity, ownership, or agreements. It works across many blockchains and has built-in privacy features using encryption and zero-knowledge proofs. Some of its key features include:

Omni-chain capability: Supports attestations across different blockchains.

Data structure: Attestations are built around key-value pairs, making them highly adaptable to different data formats.

Privacy features: Data can be encrypted or hidden using zero-knowledge proofs, ensuring that users can prove claims without revealing underlying data.

Developer incentives: Encourages innovation through funding and support for developers that integrate the Sign protocol.

Data security: Fallback mechanisms (such as Arweave storage) ensure data doesn’t get lost, even if blockchain networks face disruptions.

TokenTable

TokenTable addresses the complexities of token distribution. Through the use of smart contracts, TokenTable can provide different distribution models:

Unlocker: Fully on-chain token unlock schedules.

Merkle-based distributions: Efficient distribution using Merkle trees.

Signature-based distributions: Lightweight, cost-effective token-claiming processes.

Through TokenTable, projects can manage token vesting schedules, conduct airdrops, and handle token unlocks with minimal manual intervention. Distribution models are designed to balance cost-efficiency with on-chain verifiability and can be customized based on a project's needs.

EthSign

EthSign provides a decentralized alternative to traditional e-signature platforms. Instead of relying on traditional online signature services, users can sign contracts and agreements directly on blockchain networks.

SignPass

SignPass allows users to register and verify their identities on-chain. It connects real-world credentials with decentralized identities, helping users prove their status or qualifications without exposing unnecessary private information.

Creating and Verifying Attestations

Attestations in the Sign ecosystem involve three parties:

Attester: The entity that makes a statement about another entity (e.g., "this wallet belongs to Alice").

Subject: The entity referred to in the attestation.

Verifier: The entity that verifies if the attestation is legit.

Using the Sign Protocol, attesters generate signed statements about a subject. These attestations can then be verified by any third party, depending on access permissions and privacy settings.

The SIGN Token

The SIGN token serves as the utility and governance token for the ecosystem:

Total supply: 10 billion SIGN tokens.

Initial circulating supply: 1.2 billion SIGN (12% of total supply).

Use cases: Transaction fees, governance participation, staking incentives, and community rewards.

Sign's token distribution includes airdrops to early adopters and community members, with a focus on promoting decentralized ownership.

SIGN on Binance HODLer Airdrop

On April 25, 2025, Binance announced SIGN as the 16th project on the Binance HODLer Airdrops. Users who subscribed their BNB to Simple Earn or On-Chain Yields products from April 15 to 19 are eligible to receive the airdrops. A total of 200 million SIGN tokens were allocated to the program, accounting for 2% of the total token supply.

SIGN was listed for trading on Binance with the Seed Tag applied, allowing for trading against the USDT, USDC, BNB, FDUSD, and TRY pairs.

Closing Thoughts

Sign is laying the foundation for how verifiable claims and secure token distribution can work in the crypto space. By focusing on privacy and supporting multiple blockchains, it can offer a flexible system that suits the needs of users, developers, and institutions alike. The goal is to make it easy to verify digital interactions while still protecting sensitive information, helping build a more trustworthy digital space.
