Visão geral da arquitetura de governança e contratos inteligentes.

Visão geral de arquitetura de governança

A governança on-chain da dYdX fornece as seguintes funcionalidades:

  • Criação e votação de propostas

  • Criação de snapshots de tokens no início de uma proposta

  • Delegação separada para poderes de voto e de proposição

  • Definição de limites de governança, incluindo proposições, quórum e limites de diferenciais de voto

  • Substituição do contrato inteligente de “estratégia de governança V3”, que determina como os votos são contados

  • Configuração de vários contratos de execução que permitem:

    • melhorias de protocolo e distribuição de fundos rápidas por meio de executores de timelock curto;

    • atualizações de governança por meio de executores de timelock longo.

Existem sete contratos inteligentes que aceitam a governança da dYdX:

  • O contrato DydxToken: mantém snapshots que permitem consultas de voto de um endereço ou poder de proposição em qualquer número de bloco. Permite a delegação separada para poderes de voto e de proposição.

  • O contrato WrappedEthereumDydxToken: mantém snapshots que permitem consultas de voto de um endereço ou poder de proposição em qualquer número de bloco. Permite a delegação separada para poderes de voto e de proposição.

  • O contrato DydxGovernor: rastreia propostas e as executa por meio de contratos inteligentes de executor.

  • Os contratos de executor: criam filas, cancelam e executam transações votadas pela Governança. Se uma proposta for aprovada, as funções de chamada na proposta podem ser executadas pelo contrato de execução especificado na proposta. As transações em fila podem ser executadas após um atraso, cuja duração é determinada pelo contrato de execução.

  • ****Contrato de timelock de prioridade: o mesmo que o contrato de timelock, mas que permite que um controlador de prioridade execute transações dentro do período de prioridade (7 dias) antes do fim do atraso de timelock.

  • Contrato de estratégia de governança V3: contém a lógica da contagem de votos. Atualmente, conta os votos do token $ethDYDX, do token $wethDYDX e do $stkDYDX. Pode ser atualizado por meio de timelock longo.

  • O contrato de módulo de segurança: contém a lógica de stake para tokens $ethDYDX, tokeniza posições em stake e recebe recompensas, ao passo que mantém os direitos de voto e de proposição, além das funções de delegação dos tokens.

Código aberto e auditado

Todo o código-fonte do contrato inteligente para os contratos de governança e pools de staking pode ser encontrado em https://github.com/dydxfoundation/governance-contracts.

O código-fonte do frontend de governança hospedado na dydx.community pode ser encontrado aqui.

Todos os principais novos contratos inteligentes foram auditados pela Peckshield. Não foram encontrados problemas de segurança significativos nem de alta prioridade. A principal governança e os contratos de token são derivados dos contratos de governança da Aave, que foram auditados pelos CertiK, Certora e Peckshield e foram testados pela mainnet por meses.

Contratos de governança principal

DydxToken

O contrato DydxToken foi inspirado pela Aave. Pequenas alterações foram feitas pela equipe da dYdX.

O DYDX baseado em Ethereum está implantado em 0x92D6C1e31e14520e676a687F0a93788B716BEff5 na mainet Ethereum.

WrappedEthereumDydxToken

O contrato WrappedEthereumDydxToken é a versão wrapped do DydxToken. Os usuários podem interagir com o contrato inteligente wethDYDX e obter o wethDYDX.

O wethDYDX está implantado em 0x46b2deae6eff3011008ea27ea36b7c27255ddfa9 na mainet Ethereum.

Contratos de incentivos DYDX

Distribuidor Merkle

O contrato inteligente Merkle distribui recompensas de token $ethDYDX de acordo com uma árvore de Merkle de saldos. A árvore pode ser atualizada periodicamente com o saldo de recompensa cumulativo de cada usuário, permitindo que novas recompensas sejam distribuídas aos usuários ao longo do tempo.

Uma atualização é realizada definindo a raiz Merkle proposta para o valor mais recente retornado pelo contrato oracle. A raiz Merkle proposta pode ser ativada uma vez que o período de espera expire. Durante o período de espera, a Governança dYdX pode congelar a raiz Merkle, caso a raiz proposta se mostre incorreta ou maliciosa. As atualizações de raiz podem ser retomadas com o ShortTimelockExecutor.

O contrato inteligente Merkle foi inspirado por projetos como Uniswap e Badger. O contrato inteligente está implantado em 0x01d3348601968aB85b4bb028979006eac235a588 na mainnet Ethereum.

Módulo de segurança

O Módulo de Segurança é um pool de staking que oferece recompensas $ethDYDX aos usuários que façam o stake de $ethDYDX com vistas para a segurança do protocolo.

Módulo de liquidez

O Módulo de Liquidez é uma coleção de contratos inteligentes para o staking e empréstimos, que incentivam a alocação de fundos em $USDC para fins de criação de mercado na exchange dYdX Layer 2.

Os stakers ganham recompensas de $ethDYDX por fazer stake de $USDC. Os fundos em staked podem ser emprestados por certos parceiros pré-aprovados com base em reputação e sem garantia. Os fundos só podem ser usados na exchange L2, isto é aplicado por meio do contrato StarkProxy que interage com o contrato da Exchange StarkEx Perpetual.

StarkProxy

Este contrato permite que o proprietário empreste fundos da LiquidityStaking e use-os na StarkPerpetual. Fundos adicionais podem ser depositados pelo proprietário, e quaisquer fundos que excedam o valor emprestado podem ser retirados livremente. Este contrato interage com o contrato StarkPerpetual que foi escrito pela Starkware e anteriormente auditado e implantado.

Contratos do Tesouro

O contrato do TreasuryVester foi inspirado pela Uniswap.

O timelock curto só pode executar ações aprovadas pela governança.

Há dois investidores de tesouro e contratos de tesouro:

Como a governança controla cada tesouro, ela pode transferir fundos para qualquer endereço e/ou aprovar qualquer endereço para gastar fundos de qualquer um dos tesouros. Por exemplo, os programas de recompensas precisarão ter limites de aprovação de token definidos pela governança.

Na DIP 29, a comunidade dYdX votou para alavancar os contratos inteligentes de ponte de tesouro de recompensas e de ponte de tesouro da comunidade, o que permitiu a migração de ethDYDX disponível no Tesouro de tesouro de recompensas e tesouro da comunidade para a Cadeia dYdX.

Cada investidor do tesouro fará a aquisição de tokens de forma linear ao longo de ~5 anos (3 de agosto de 2021 - 3 de agosto de 2026) para o tesouro correspondente. Como os contratos de investidores são imutáveis na implantação, a comunidade dYdX votou para definir o destinatário dos contratos de investidores para os seguintes endereços:

Contratos periféricos

Recompensas da Chainlink Oracle-Powered (Recompensas de provedores de liquidez e trades)

O objetivo deste sistema é calcular e publicar, por meio de uma rede descentralizada de signatários de oracle (oracle signers), as recompensas de token ethDYDX obtidas pelos traders usando a exchange dYdX layer 2. As recompensas são armazenadas em uma árvore de Merkle, que contém as recompensas cumulativas obtidas por cada usuário desde o início do programa de distribuição. A cada epoch, a raiz Merkle é atualizada no contrato inteligente MerkleDistributorV1 para refletir as recompensas obtidas na epoch anterior.

Integramos o sistema da Chainlink Oracle para postar dados de recompensas on-chain. Usamos IPNS para postar os dados de trades usados pela Chainlink para criar a árvore de Merkle. Usando IPNS, podemos postar os dados de trades para a epoch mais recente no mesmo link de IPNS que as epoch anteriores, o que significa que a localização dos dados não mudará.

Após calcular as recompensas apropriadas a partir dos dados de trades brutos, a Chainlink posta as recompensas da árvore de Merkle na IPFS. O CID IPFS com os dados da árvore de Merkle é armazenado no contrato de distribuidor Merkle juntamente com a raiz Merkle para as recompensas dessa epoch.

O fluxograma a seguir mostra a arquitetura do sistema de Recompensas da Chainlink Oracle-Powered:
