How to get started with Sei?

Beginning your journey with the sei chain involves several straightforward steps, particularly if you have prior experience with crypto wallets and token staking.

Creating a Sei wallet requires selecting a compatible wallet for the Sei blockchain. Ethereum wallets can connect to Sei by adding it as a custom network. Compass Wallet offers Sei-specific features including in-wallet staking and portfolio overview functionality. Compatible wallets provide support for Sei and numerous other decentralized networks, enabling unified management of crypto activities.

Linking wallet addresses takes advantage of Sei's support for both Ethereum (0x) and Sei addresses, allowing hassle-free asset management across multiple chains. Address linking occurs through the Sei dashboard, simplifying cross-chain interactions.

Exploring DApps becomes possible once your wallet is configured, allowing access to Sei's expanding ecosystem. Options range from liquid staking projects like Silo to onchain trading platforms available within the sei chain ecosystem.

staking on Sei utilizes the Delegated Proof of Stake (dPoS) mechanism, where token holders can delegate to validators, helping secure the network while earning staking rewards. SEI tokens can be staked directly through compatible wallets, providing a straightforward entry point for network participation.

What are SEI's tokenomics?

The SEI token serves as the foundation of Sei's decentralized Proof-of-Stake blockchain, fulfilling multiple essential functions within the ecosystem. The token is utilized for transaction fees, validator staking through delegation or direct operation, governance participation allowing holders to influence protocol direction, collateral provision for applications built on the sei chain, fee market operations enabling transaction prioritization through validator tips, and trading fee payments for platforms built on the network.

The total supply of SEI is capped at 10 billion tokens, with the majority allocated to community and project development initiatives. The distribution allocates 51% to community purposes, broken down into an Ecosystem Reserve (48%) covering staking rewards for validators and users, plus ecosystem initiatives including grants and incentives for developers and builders. The Foundation Treasury receives 9% to fund ongoing Sei Foundation operations, while the Launch Pool receives 3% to support future development.

Importantly, Sei has no planned airdrops outside its domain and conducts no token sales. As the sei chain evolves, the community's governance may implement changes to token distribution and utility.

The governance of the Sei blockchain

Governance on the sei chain operates through a decentralized model where stakers holding locked Sei tokens can propose, discuss, and vote on network changes, empowering community participation in important decisions.

The proposal process follows a structured path: anyone can submit a proposal by paying a deposit, initiating a deposit period where community members can add deposits. If the minimum deposit threshold is met, the proposal advances to a voting period where the community casts votes. Finally, a result period tallies votes and finalizes outcomes.

Voting options include Yes (agreement with the proposal), No (disagreement), No with Veto (strong disagreement resulting in deposit burning if passed), and Abstain (participation without taking a position).

Proposal validity requires meeting a quorum, representing a minimum percentage of all staked Sei that must participate in voting. Common proposal types include parameter changes adjusting network module settings, community spend proposals suggesting fund allocation from the community pool, and text proposals covering broader decisions or directional shifts.

The voting process breakdown begins with submission, initiating a 2-day deposit period. If the proposal accumulates 3,500 Sei or more in deposits, it advances; otherwise, deposits are burned. A 5-day voting period follows, concluding with result tallying. For passage, proposals require 33.4% of all staked Sei to vote (quorum), less than 33.4% voting "No with Veto," and more Yes votes than combined No/No with Veto votes.

Deposits serve as spam protection: proposals failing to meet deposit thresholds are scrapped with deposits burned. Proposals reaching the voting stage receive deposit returns unless vetoed.

Conclusion

With the successful launch of Sei V2, the sei chain has established itself as a compelling contender in the layer-1 blockchain space. The platform's emphasis on speed, scalability, and security creates a foundation for enhanced efficiency and user experience across developers, traders, and community members.
