​

Portal Enterprise Service Agreements

​

Portal Pools. Lambda Revenue Pool

​

Cloud. PostgreSQL version support

​

Portal MCP Server v0.7.5 → v0.7.7

• Tool catalog overhaul. Audited every public tool and consolidated down to ~20 core tools (23 with Substrate), with a unified description style, input schema, response envelope, and routing metadata.
• Substrate support. Three new tools (portal_substrate_get_analytics, portal_substrate_query_events, portal_substrate_query_calls) bring Polkadot- and Kusama-style chains to parity with EVM, Solana, Bitcoin, and Hyperliquid.
• Interactive panel UI (v1). New _ui envelope (panels, metric cards, follow-up actions) renders results as a dashboard in MCP-aware clients instead of raw JSON.
• LLM next-step hints. Every response now includes structured follow-up guidance so multi-step investigations work without hand-holding.
• Experimental EVM OHLC tool. portal_evm_get_ohlc builds candles from Uniswap v2/v3/v4 and Aerodrome Slipstream swaps with a recent-trades tape.
• BTC and Hyperliquid tools. Available since v0.7.5.

​

Substrate OpenAPI Schema

​

New Chains & Datasets

• MegaETH. Hotblocks support added for both mainnet and testnet.
• ADI. Added as a hotblocks-only dataset.
• Alpen. Onboarded (chain ID 8150) with archival data.
• Hyperliquid replica_cmds. Both S3 archival and real-time ingestion are now live.
• Solana token balance siblings. New transactionTokenBalances and transactionBalances flags for the tokenBalances filter, letting users retrieve all token balance updates for the parent transactions of matching balances without overfetching.
• Aptos & Aleo. Initial onboarding research completed.

​

Discontinued Substrate Chains

​

Bug Fixes

• Better errors for missing columns. “Column not found” errors from the query engine now correctly return HTTP 400 (Bad Request) instead of a generic 500, making queries much easier to debug.
• Hotblocks memory optimization. Improved memory management in hotblocks services with usage limits and proper cleanup for stable performance under high load.

​

Bitcoin on Portal

• Feb 23. Archival data synced, Bitcoin query support added to Portal
• March 19. Versioned datasets introduced, majority of workers upgraded to >2.9
• March 24. Dataset and hotblocks deployed to public portal

​

Portal & Network

• Versioned datasets. New mechanism allowing datasets to be restricted to workers running a minimum client version, enabling safe rollout of new chain support
• Worker execution time breakdown. Worker logs now show per-step timing (query parsing, execution, compression, signing, serialization)
• Worker auto-reconnect. Workers now automatically reconnect if initial network bootstrapping fails
• Error propagation. Query engine errors like "column not found" now return proper 400 Bad Request instead of 500 Server Error
• Parent hash check fix. Fixed incorrect parent block hash validation in EVM datasets
• Head monitor log fix. Fixed log spam (2.5M logs/30min)
• SQL query engine. Integrated into the network for future SQL query support

​

Portal MCP Server v0.7.5

• Bitcoin support. 5 new tools for querying Bitcoin transactions, inputs, outputs, analytics, and time series
• Tool consolidation. Consolidated from 41 to 29 tools by converting 13 standalone tools (traces, state diffs, NFT transfers, gas analytics, etc.) into include flags on core query tools
• Per-chain analytics and time series. New analytics and time series tools for Solana, Bitcoin, and Hyperliquid with chain-specific metrics (TPS, fee trends, volume, trader rankings)
• Retry logic. Added 503/409/429 retry with exponential backoff for production reliability
• Timeframe estimation. Improved short timeframe handling; skips timestamp API for windows under 2h and uses per-chain block time estimates
• Fuzzy dataset resolution. "base" resolves to base-mainnet, "eth" to ethereum-mainnet
• Timeframe parameter. All query tools support timeframe (e.g., "24h", "7d") instead of manual block ranges
• Response size cap. Capped at 50KB to prevent context overflow in AI clients
• Chunked fetching. Hyperliquid and Solana queries use chunked fetching to prevent memory issues
• Known limitation. Large unfiltered queries on high-TPS chains (Solana, Hyperliquid) can still hit memory limits; use tight filters and small block ranges on dense chains

​

AI Agent Skills v1.1.1
