How to get started with Sei?

Beginning your journey with Sei involves several straightforward steps, particularly if you're already familiar with cryptocurrency wallets and token staking. Understanding how to interact with Sei contract addresses safely is fundamental to using the platform effectively.

The first step involves creating a Sei-compatible wallet. If you already use an Ethereum wallet, you can typically connect it to the Sei blockchain by adding Sei as a custom network in your wallet settings. Compass Wallet offers a specialized solution designed specifically for Sei, providing features like in-wallet staking, portfolio overview functionality, and integrated contract address management. Alternatively, compatible wallets support Sei alongside numerous other decentralized networks, making them excellent choices for users who want to manage all their cryptocurrency activities in a single interface.

Linking wallet addresses represents an important step in maximizing Sei's functionality. The platform's support for both Ethereum (0x) and Sei native addresses enables users to manage assets across multiple chains without complexity. Through the Sei dashboard, users can easily link their wallet addresses, facilitating smooth cross-chain interactions and asset management. When adding custom tokens or interacting with dApps, always verify you're using the correct Sei contract address from official sources.

Exploring decentralized applications (DApps) built on Sei allows users to experience the platform's capabilities firsthand. The Sei ecosystem includes a growing collection of applications spanning various use cases. Projects like Silo offer liquid staking opportunities, while DragonSwap provides on-chain trading functionality. Before interacting with any dApp, verify the official Sei contract address through trusted channels to avoid fraudulent contracts. This diverse application ecosystem ensures users can find services matching their specific interests and needs.

Staking on Sei provides an opportunity to participate in network security while earning rewards. The platform utilizes a Delegated Proof of Stake (dPoS) system where users can delegate their tokens to validators. This delegation helps secure the network, and in return, delegators receive staking rewards. Compatible wallet applications simplify this process, allowing users to stake SEI tokens directly through the wallet interface. Getting started with Sei—whether for staking, trading, or exploring DApps—proves straightforward once your wallet is configured, your addresses are linked, and you understand how to verify Sei contract addresses safely.

What are SEI's tokenomics?

The SEI token serves as the native cryptocurrency powering the Sei blockchain, fulfilling multiple essential functions within the ecosystem. Understanding these tokenomics, including how SEI relates to contract addresses on the platform, provides insight into the platform's economic design and incentive structures.

Transaction fees represent the most fundamental use of SEI tokens. All network operations, including contract interactions and deploying new contract addresses, require users to pay fees in SEI, creating consistent demand for the token while compensating validators for their computational resources and network maintenance.

Validator staking constitutes another critical function. Token holders can delegate SEI to validators or stake sufficient amounts to operate their own validator nodes. This mechanism secures the network through economic incentives—validators must act honestly to avoid losing their staked tokens through slashing penalties. The staking system ensures network security scales with the platform's value and usage.

Governance rights accompany SEI token ownership, enabling holders to participate in protocol decision-making. This democratic approach ensures the community guides the platform's evolution, voting on proposals ranging from technical parameters to treasury allocations.

SEI tokens can serve as collateral within applications built on the platform. DeFi protocols may accept SEI as collateral for loans or liquidity provision through their smart contract addresses, integrating the native token into the broader ecosystem and creating additional utility.

The fee market mechanism allows users to include tips for validators, prioritizing their transactions during periods of high network activity. Delegators share in these tips proportionally to their stake, creating additional incentives for token holders.

For exchanges built on Sei, SEI tokens can be used to pay trading fees, further integrating the token into the platform's core use cases. When interacting with exchange contracts, always verify the official Sei contract address.

The total supply of SEI is capped at 10 billion tokens, with the majority allocated to community and ecosystem development. This distribution reflects Sei's commitment to decentralization and long-term sustainability. Community tokens represent 51% of the total supply, broken down into several categories. The Ecosystem Reserve comprises 48% of the total supply, supporting staking rewards for validators and delegators while funding ecosystem initiatives through grants and incentives for developers and contributors. Some tokens have been pre-allocated to projects meeting specific developmental milestones.

The Foundation Treasury holds 9% of tokens, supporting the ongoing operational expenses of the Sei Foundation. The Launch Pool accounts for 3% of tokens, reserved for future development initiatives.

Importantly, Sei has explicitly stated no plans for airdrops outside its official channels and no intentions for initial coin offerings or community sales. This approach aims to prevent scams and maintain fair token distribution. Users should be cautious of fraudulent contracts claiming to offer SEI tokens and always verify the authentic Sei contract address through official documentation. As with any blockchain project, the governance structure may evolve over time based on community decisions.

The governance of the Sei blockchain

Sei's governance model embodies the decentralized ethos of blockchain technology, empowering stakeholders to collectively guide the platform's evolution. This democratic approach ensures the network develops according to community consensus rather than centralized authority.

The proposal process begins when any community member submits a governance proposal along with a required deposit. This deposit requirement serves as spam protection, ensuring only serious proposals reach the voting stage. Following submission, the proposal enters a deposit period during which other community members can contribute to the deposit. If the minimum deposit threshold is met, the proposal advances to the voting phase; otherwise, it's rejected and deposits are burned.

The voting period allows all stakers to cast their votes, choosing from four options. A "Yes" vote indicates agreement with the proposal. "No" represents disagreement while "No with Veto" signals strong opposition—if this option receives sufficient support, the proposal fails and deposits are burned as a penalty. "Abstain" allows participation in the voting process without taking a position, contributing to quorum requirements without influencing the outcome.

For a proposal to be considered valid, it must achieve quorum—a minimum percentage of all staked SEI must participate in the vote. This requirement ensures proposals reflect broad community engagement rather than the preferences of a small minority.

Common proposal types include parameter changes that adjust technical settings in network modules, community spend proposals suggesting allocations from the community treasury, and text proposals covering broader strategic decisions or directional shifts for the platform.

The detailed voting process breakdown provides clear timelines and thresholds. Following submission, a two-day deposit period begins. If the proposal accumulates at least 3,500 SEI in deposits, it proceeds to voting; otherwise, deposits are burned. The voting period lasts five days, during which community members select their preferred option. For a proposal to pass, several conditions must be met: at least 33.4% of all staked SEI must participate (quorum), less than 33.4% can vote "No with Veto," and "Yes" votes must exceed combined "No" and "No with Veto" votes.

The deposit mechanism serves dual purposes: it prevents spam proposals while ensuring proposers have skin in the game. Proposals reaching the voting stage return deposits to contributors unless the proposal is vetoed, in which case deposits are burned. This structure incentivizes thoughtful proposal submission while maintaining governance efficiency.

Conclusion

Sei represents a significant evolution in blockchain technology, specifically engineered to address the performance limitations that have hindered decentralized trading and application development.
