PROFILE
Rhaki
Over six months, this developer contributed to the left-curve/left-curve repository by building and maintaining deployment automation, blockchain integrations, and operational tooling. They delivered features such as Hyperlane mainnet configuration, Points Bot and Perps Bot deployment enhancements, and vault deposit scripts, focusing on reliability and observability. Their technical approach emphasized configuration management and infrastructure as code, using Ansible, Docker, and Rust to streamline deployments and improve testnet and mainnet readiness. They also addressed bugs in validator set alignment and cryptographic signature integrity, while refining monitoring, logging, and code quality. Their work enabled safer, faster deployments and more robust blockchain operations.

Apr 1, 2026Summary for 2026-04: The team delivered production-ready features and reliability improvements across the Left Curve deployment stack, with a clear focus on deployment operability, mainnet readiness, and liquidity tooling. Key features delivered include: (1) Points Bot deployment and operational enhancements: added a Docker image tag parameter for deployments, mainnet-ready inventory and monitoring (Hetzner1 with Prometheus scraping), updated deployment playbooks, and operational tooling to stop Hyperlane agents and start dango httpd independently from CometBFT; event duration updated from 24h to 38h for improved reliability. (2) Perps Bot mainnet deployment: Ansible-driven deployment configuration, Docker settings, and environment configuration enabling a reliable perpetuals trading bot on mainnet. (3) Vault deposits for ETH-USD on development network: script to enable ETH-USD vault deposits with tuned spread, liquidity weight, and max quote size to improve liquidity and trading efficiency on devnet. Major bugs fixed: (a) Hyperlane relayer configuration enhancements: support for an optional custom Ethereum RPC URL and an ignoreReorgReports option to improve resilience to chain reorganizations. (b) EIP-712 address hash computation fix to ensure integrity of signatures. Other improvements: time utilities for Duration conversions and code formatting improvements to enhance readability and maintainability. Overall impact: increased deployment reliability and observability, stronger mainnet readiness, and improved liquidity tooling in development, enabling faster iteration and safer operations. Technologies demonstrated: Ansible, Docker, Vault integration, Prometheus observability, Hyperlane tooling, EIP-712 cryptographic considerations, and general code quality practices.

Jan 1, 2026January 2026 — Left Curve (left-curve/left-curve) delivered Hyperlane mainnet configuration with a new key management script and updated Dango blockchain configuration files. In addition, Hyperlane logging verbosity was optimized by lowering the log level from debug to info to reduce noise. No major bugs were fixed this month. Overall impact includes improved deployment readiness, stronger key lifecycle security, and clearer operational telemetry, enabling faster deployments and easier incident response. Technologies demonstrated include Hyperlane integration, secure key management practices, and configuration-driven deployment.
