StaFiStaking Letter #9: A Simple Guide to Understanding FIS Burn and Treasury
StaFi Chain has recently activated and launched its FIS burn mechanism. While we will see the specific amount of the first FIS burn in about thirty days, the community's focus has primarily been on the results rather than understanding the mechanism itself, leading to many misconceptions. This letter aims to briefly explain the FIS burn mechanism and treasury FIS operations based on the burn proposal mechanism.FIS Burn Proposal: proposals.stafi.io/proposal/sip11/StaFi Node v0.6.3: github...
StaFiStaking Letter #19: Introducing the Liquid Staking Vault (LSV)
IntroductionAt StaFi, we’ve been pioneering Liquid Staking as a Service (LSaaS) to bring liquidity to PoS tokens. Today, we want to introduce a brand new idea which is the new infrastructure module designed specifically for non-PoS tokens, dApps, and appchains:Liquid Staking Vault (LSV) = Staking Vault + Liquid Staking TokenUnlike traditional LST protocols designed around PoS consensus mechanisms, the LSV framework is built entirely at the contract layer — enabling any project, including non-...
StaFiStaking Letter #21: RWA Tokenization Integrated into the LSaaS Stack
The RWA TrendReal World Asset (RWA) tokenization is rapidly becoming one of the most compelling trends in blockchain. As of mid-2025, over $8 billion worth of RWAs—ranging from U.S. Treasury bonds, gold, to real estate—have already been tokenized and deployed across major chains like Ethereum, Polygon, and Solana (source: rwa.xyz, 2025 Q2 report). This growth is not just speculative; it reflects a structural shift. By putting RWAs on-chain, blockchain infrastructure enables greater liquidity,...

StaFi Hub is transitioning from an app chain to a contract layer model due to prior security challenges. This migration involves moving rATOM to Neutron, which supports CosmWasm smart contracts. The new rATOM is built using StaFi LSaaS’s CosmWasm LSD Stack, exemplifying enhanced security and scalability.
The x/wasm module, the root of CosmWasm, is a Cosmos SDK module enabling smart contracts to execute on the CosmWasm virtual machine. CosmWasm itself refers to the whole ecosystem built around it with a mission to make smart contracts development easy and reliable. The focuses of the CosmWasm platform are security, performance, and interoperability. It is tailored for a tight integration with Cosmos SDK and to build IBC contracts.
The important thing about CosmWasm smart contracts is their transparency. Every smart contract instance has its unique address on the chain, and it can act just like any other account on chain. It is easy to implement communication between two smart contracts on the same chain. CosmWasm standard library provides simple utilities to communicate with non-CosmWasm modules on the chain. That includes common Cosmos modules like bank or staking and any custom module unique for a particular chain. Finally, CosmWasm is built around the IBC(opens in a new tab) and provides a simple API to communicate with other chains and contracts using IBC-based protocols.
Cosmos LSD Stack is devoted to help developers building liquid staking project in Cosmos ecosystem, and designed to provide a comprehensive set of solutions related to Cosmos LSM, CosmWasm, commission fee management, validator set management, and user operations: stake, unstake, withdraw.
Given the complexity of Cosmos ecosystem, StaFi Cosmos LSD Stack supports most chains that either adhere to the ICS-27 Interchain Protocol or CosmWasm. However, it is not compatible with a few chains, such as Irisnet(IRIS), which do not support either.
Stack can be directly deploy on the target chains if they support CosmWasm
Conversely, for ICS-27 Protocol chains, Our Stack deploys on Neutron, which is a permissionless smart contract platform, and gives programmable operations of ICA and ICQ on the target chain
The Stack current development progress:
Ready to use for ICS-27 protocol chains
Smart contracts for CosmWasm native chains are under development, stay tuned
Understanding More: https://docs.stafi.io/lsaas/architecture_cosmos_lsd/
Go to LSaaS App, and select ATOM LST
Connect your wallet, configure contract parameters, and wait for the contract deployment.

ICQ is an abbreviation for Interchain Queries which allow smart contract to make queries to a remote chain. An ICQ Relayer is a required component for making them possible. It acts as a facilitator between the Neutron chain and a querying chain, gathering queries that are needed to be performed from the Neutron, actually performing them, and eventually making the results available for the Neutron’s smart contracts. Read full ICQ relayer documentation here

Given the limitation of smart contracts, they are not self-executing, and require an external force to trigger their functions. Relay is a service to drive LSD to properly process its own internal states, such as dealing with delegating, undelegating, distributing rewards and calculating the rate between LST and the original coin. We introduce era concept to define how often the smart contract should be called. Most of the time, an era is 24 hours long.

Cosmos LSD App is a user interface where users can stake, unstake and get latest information about the project. As a convention in web3 all API users interact with are directly from the RPC configured in wallet, so the app is a pure DApp.

StaFi is a leading Liquid Staking infrastructure provider and protocol for PoS chains. Its Liquid Staking as a Service (LSaaS) framework enables developers to create Liquid Staking Tokens (LSTs) and Liquid Re-staking Tokens (LRTs) across ecosystems like ETH, EVM, BTC, CosmWasm, and SOL. By issuing rTokens (e.g., rETH, rMATIC, rBNB), StaFi unlocks the liquidity of staked assets, allowing users to earn staking rewards while retaining the flexibility to engage in DeFi. With support for major blockchains such as Ethereum, Solana, Polygon, BNB Chain, and Cosmos, StaFi bridges liquidity and security in Proof-of-Stake networks.
