How to get started with Sei?

Getting started with the sei network involves several straightforward steps. First, users need to create a Sei-compatible wallet. Ethereum wallets can connect to the sei network blockchain by adding it as a custom network. Compass Wallet offers Sei-specific features like in-wallet staking and portfolio overview, while other compatible wallets support Sei along with numerous other decentralized networks, enabling unified management of crypto activities.

Linking wallet addresses represents a convenient feature, as the sei network supports both Ethereum and Sei addresses. Users can link their wallet addresses through the Sei dashboard, facilitating simple and fluid cross-chain interactions.

Exploring the ecosystem comes next, with users able to discover Sei's growing collection of dapps. The sei network ecosystem includes liquid staking projects like Silo and onchain trading platforms like DragonSwap, offering diverse opportunities for engagement.

For staking, the sei network employs a Delegated Proof of Stake system where users can delegate tokens to validators. This participation helps secure the network while earning staking rewards. SEI tokens can be staked directly through compatible wallets, making the process accessible and straightforward.

What are SEI's tokenomics?

The SEI token serves multiple crucial roles within the sei network ecosystem. As the native token of this decentralized Proof-of-Stake blockchain, SEI functions as the medium for transaction fees, validator staking, governance participation, collateral for applications, fee market operations, and trading fees on Sei-based exchanges.

The total supply is capped at 10 billion tokens, with the majority allocated to community and ecosystem development. The community receives 51% of total tokens, broken down into an Ecosystem Reserve (48%) and Foundation Treasury (9%). The Ecosystem Reserve funds staking rewards for validators and delegators, as well as ecosystem initiatives through grants and incentives for developers and network participants. The Foundation Treasury supports ongoing operations of the Sei Foundation.

A Launch Pool allocation of 3% supports future development initiatives on the sei network. Importantly, Sei has no plans for airdrops outside its domain and conducts no ICOs or community sales. The tokenomics structure prioritizes long-term sustainability and community-driven growth, though governance mechanisms allow for potential adjustments as the blockchain evolves.

The governance of the Sei blockchain

Governance on the sei network operates through a decentralized model where stakers who lock up their tokens can propose, discuss, and vote on network changes. This system empowers the community to participate in important decisions affecting the blockchain's future.

The proposal process follows a structured path: anyone can submit a proposal by paying a deposit, after which a deposit period allows the community to add deposits. If the minimum deposit is met, the proposal advances to a voting period where the community votes, followed by a result period where outcomes are tallied and finalized.

Voting options include Yes (agreement), No (disagreement), No with veto (strong disagreement resulting in burned deposits if passed), and Abstain (participation without taking a side). For proposal validity, a quorum representing a minimum percentage of all staked Sei must participate in the vote.

Common proposal types on the sei network include parameter changes to adjust network module settings, community spend proposals for fund allocation, and text proposals covering larger decisions or directional shifts. The voting process typically spans a 2-day deposit period requiring 3,500 Sei or more, followed by a 5-day voting period. 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 No/No with Veto combined.

Deposits serve as spam protection, with unsuccessful proposals resulting in burned deposits, while proposals reaching the voting stage receive deposit returns unless vetoed.
