Definições
LST (Liquid Staking Token): token ERC-20 que representa ETH staked. Holder ganha staking yield (cerca de 3,1-3,5% APR em maio 2026) sem operacional próprio. Examples: Lido stETH, Rocket Pool rETH, Coinbase cbETH, Frax sfrxETH.
LRT (Liquid Restaking Token): token ERC-20 que representa ETH restaked via EigenLayer (ou similar). Holder ganha staking yield + restaking AVS yields. Examples: Ether.fi eETH, Renzo ezETH, Kelp rsETH, Puffer pufETH.
Yields comparados
LST yield em maio 2026: 3,1-3,5% APR (varies by LST e fees). Source: staking rewards from Ethereum beacon chain.
LRT yield em maio 2026: 4,5-7,5% APR total (varies significantly by LRT e AVS exposure). Source: base staking + AVS service fees.
Spread (LRT - LST): 1,5-4% APR. Compensation for additional risk layers. Whether worth it depends on individual risk tolerance.
Riscos compostos: LST
Risk 1: smart contract LST. Lido, Rocket Pool, etc são audited but new bugs surface in DeFi periodically.
Risk 2: node operator risk. Operators can be slashed for misbehavior. LSTs typically have insurance funds + diversified operator set para mitigate.
Risk 3: depeg risk. stETH famously depegged to 0,95 ETH em junho 2022 (3AC crisis). For LSTs in low-liquidity pools, depeg can be significant in stress events.
Risk 4: governance. LDO token holders govern Lido. Decisions can affect stETH operations.
Riscos compostos: LRT
Risk 1: tudo dos LST risks (LRT é built sob LST).
Risk 2: EigenLayer protocol risk. EigenLayer é newer (mainnet 2024), less battle-tested.
Risk 3: AVS slashing risk. Each AVS the LRT exposes to has its own slashing conditions. Misbehavior (operator) ou bug in AVS can cause slashing of staked ETH.
Risk 4: LRT protocol risk. Ether.fi, Renzo, etc add own layer of smart contracts + governance.
Risk 5: AVS portfolio risk. Different LRTs delegate to different AVS portfolios. Concentration in single AVS that fails can cascade.
Risk 6: depeg amplified. LRTs in less mature secondary markets — depeg more likely em stress.
Liquidity comparada
stETH é most liquid LST. Curve stETH/ETH pool tipically TVL >$1B, slippage <0,1% para trades up to $10M.
rETH liquid mas smaller (TVL pools ~$200M).
LRTs: Ether.fi eETH é most liquid LRT (Curve pools ~$300M TVL). Renzo ezETH less liquid. Smaller LRTs (Puffer, Kelp) significantly less liquid — slippage 0,5-2% for $1M+ trades.
Implication: large holders should prefer stETH for in/out flexibility. Smaller positions can use LRTs.
Lockups e withdraw queues
Em maio 2026, ETH withdraw queue (from beacon chain) é cerca de 8-15 dias (varies). LSTs can be redeemed natively via this queue (slow) ou sold em secondary market (fast).
LRTs adicionalmente have AVS unbonding queues — variable by AVS, can range 1-21+ days. Total queue para full LRT exit can be longer than LST.
Implication: LRTs less suitable for capital that may need rapid mobilization.
Decisão framework
Risk-averse, long-term ETH holder: prefer LST (stETH ou rETH). Acceptable 3,1-3,5% yield, lower risk profile.
Moderate risk tolerance, looking for yield: mix LST + LRT. 70% stETH + 30% eETH é razoável.
High risk tolerance, sophisticated DeFi user: LRT exposure higher (50%+), with careful selection of LRT protocol e AVS portfolio.
Active trader needing liquidity: prefer holding ETH unstaked ou LST (not LRT). Capital flexibility matters more than marginal yield.
Implicação para o investidor brasileiro
Tax treatment: LST/LRT yields no Brasil tipically treated as rendimento, tributável similar aos staking rewards diretos. Verificar com contador.
Withdraw considerations: OFFCODE não custodia LSTs ou LRTs directly (depósitos são na chain de origem). Para usar, withdraw ETH para self-custody wallet e interact com protocols directly.
Aviso YMYL: LSTs e LRTs são DeFi products with inherent risks. Track record varies. Not equivalent to spot ETH em risk profile. Position size em proporção ao risk tolerance, mantenha hard-cap em DeFi protocols por security headroom.
