Solana Blockchain Developer

@NerdLad

Hey there, Are you already indexing Solana accounts and token holder distributions via RPC providers (like Helius, Triton, or custom Geyser plugin), or do you expect me to set up the raw data ingestion layer? Should the std. deviation and profit-in-holders logic be computed in real-time (per query) or batched/streamed (to save RPC costs and latency)? From what you describe, the core of this job is building Solana-native analytics: Fetching token account data, computing entry price vs current price to estimate % holders in profit. Writing routines that maintain rolling historical std. deviation of token prices, stored in a local DB for faster retrieval. Tracking changes in active addresses using time-bucketed signatures from Solana RPC or Geyser event streams. Updating your existing “SOL Filter” so it matches parity with your ETH/BSC/BASE/POLYGON stack. I’ve worked on similar Solana pipelines before: setting up Geyser plugins to stream token account updates, then aggregating into Postgres/ClickHouse for fast queries. One project involved computing volatility bands and holder profit ratios for a memecoin index; another used Triton RPC + WebSocket feeds to monitor active wallets and filter bot-driven spikes. Looking forward to chatting, Best Sython

@zlatkoa2

Your ETH/BSC/BASE/POLYGON filters already give you an edge—bringing Solana up to that same level means tackling its unique on-chain data structures with precision. I’ve worked directly with Solana RPCs, Helius APIs, SPL token programs, and account indexing, so extracting holder profit %, computing historical volatility (std. dev), and tracking active addresses is something I can deliver cleanly and efficiently. What I’d do: Profitability metrics: build a pipeline to analyze token holders’ average entry vs. current market, giving you accurate % in profit. Volatility data: implement rolling std. dev. calculations across flexible lookbacks for historical signal strength. Active address tracking: query Solana transactions/accounts across customizable timeframes, surfaced in a performant data model. SOL Filter upgrade: refactor your existing codebase for Solana’s specifics, align with the same standards you’ve set for other chains. Recently, I shipped a Solana analytics integration that scaled from ~5k to 100k daily queries while maintaining sub-second response times—optimizing RPC calls and caching was the key. I can jump in quickly and get your SOL filter aligned with the others. Do you want me to start by auditing your current Solana pipeline and proposing the most efficient way to compute these metrics at scale?

I’m a Solana-native dev with hands-on experience building indexers, DEX parsers (Raydium/Orca), and data pipelines using Helius APIs, RPC scanners, and @solana/web3.js. I can upgrade your SOL filter to match your EVM stack with clean, optimized code. What I’ll deliver: - % Holders in Profit: Snapshot token accounts, rebuild cost basis from DEX fills/transfers, mark-to-market with Pyth/Jupiter prices. - Std Deviation & Historical Vol: Compute rolling σ, z-scores, Bollinger using trade/candle data. - Active Addresses: Track unique signers with flexible windows, segment whales/new wallets, measure concentration. - Filter Upgrade: Robust Node/Rust pipeline, rate-limit aware RPC, backfills, and materialized views for fast queries. Stack: TypeScript + Rust, Redis/ClickHouse/Postgres, BullMQ orchestration, unit + integration tests, Grafana dashboards. Timeline: - Week 1: Profit calc MVP + parsers. - Week 2: Std dev + active address metrics. - Week 3: Optimizations, backfills, docs, and handoff. I’ll integrate directly into your current repo, deliver strong performance and reliability, and provide clear documentation so your team can extend it easily. Ready to turn Solana data into power.

@Ekarthaan

Hi Karoly A., I recently completed a similar project. Message me so I can show you that sample. Question: How do you define “holders in profit” on Solana: strict FIFO cost-basis per wallet from on-chain swaps (Raydium CLMM/AMM, Orca Whirlpools, Phoenix) plus transfers, or a price-at-receipt heuristic? And what’s the canonical price feed (Jupiter agg candles vs Pyth) and lookback? Suggestion: Implement a lean Solana-native indexer: Helius webhooks/Geyser → decode SPL Token/Token-2022 + DEX events → maintain per-mint, per-holder FIFO cost basis and balances. Use getProgramAccounts with mint memcmp + dataSlice for initial holder snapshots; then stream deltas only. Compute rolling std dev/vol with Welford’s online algorithm for 1m/5m/1h/24h windows; store micro-buckets in ClickHouse for fast historical queries. Active addresses = unique signers touching ATAs, new ATA creations, and swap signers per timeframe (HyperLogLog to de-dupe at scale). Price from on-chain pools (Raydium/Orca) with Phoenix mid, fallback to Pyth/Jupiter for continuity. Optimize RPC with getMultipleAccounts batching, priority fees, and retry/backoff. Expose clean endpoints: % holders in profit, historical std dev, active address delta, and updated SOL filter signals with thresholds. Kindly send me a message, lets discuss in detail and my portfolio is uploaded here and on my website. Best Regards, Sid CTO and Co-Founder of Ekarthaan
