SpiderSwap

SpiderSwap launched in 2023 as a community-first DEX aggregator on Solana, routing token swaps across multiple automated market makers to deliver best-rate execution. The project has since evolved into Carbium, a full-stack Solana infrastructure platform that retains the original SPDR token and expands the product surface to include institutional-grade RPC nodes, a Swap API, token data services, and a Swiss-hosted bare-metal validator.

Origins: DEX Aggregation on Solana

SpiderSwap was built to solve a straightforward problem: Solana's liquidity is fragmented across dozens of AMMs and liquidity pools, so any single-venue swap leaves execution quality on the table. The aggregator queries multiple venues simultaneously, selects the path with the lowest slippage and best price, and executes the trade in a single transaction.

The project positioned itself explicitly against the venture-capital playbook from the outset. The SPDR token launched with a capped supply of one billion tokens and no presale, no VC allocation, no seed round, and no discounted OTC sales. Every participant entered at the same market price. The intent, stated in the original whitepaper, was a swap platform run "by the community for the community" and governed entirely by SPDR holders.

Fee redistribution was embedded in the token design: 15% of platform transaction fees flow into a single-staking SPDR pool, rewarding holders who lock their tokens rather than relying on inflationary emissions.

Swap Mechanics

The aggregator's core routing logic navigates across Solana's liquidity landscape — covering Raydium, Orca, and other major AMMs — and constructs multi-hop paths when a direct pair lacks depth. The engine supports reverse quoting (calculating the input required to receive a specific output amount) and bulk token management, making it practical for treasury operations and programmatic trading beyond casual retail swaps.

The platform launched in beta on spiderswap.io, with the live engine becoming publicly accessible in the first half of 2024.

Rebrand and Expansion: SpiderSwap Becomes Carbium

As of 2024, spiderswap.io redirects permanently to carbium.io. The project describes Carbium as "a full-stack Solana infrastructure provider born from the evolution of SpiderSwap and SPDR." The original swap aggregator remains operational at app.carbium.io, now integrated into a wider product family.

The rebrand reflects a deliberate shift in scope. Where SpiderSwap addressed end-user trading, Carbium targets developers, trading teams, and infrastructure operators who need low-level Solana primitives as much as they need a DEX interface.

The Carbium Product Stack

Carbium organizes its infrastructure into five distinct surfaces:

DEX (app.carbium.io) — The browser-based trading interface inherited from SpiderSwap. Wallet-connected users swap tokens with MEV protection via Jito integration, gasless transaction execution (no SOL required for gas), and best-rate routing across aggregated liquidity. The interface also surfaces the SPDR token pair for direct trading.

Swap API (api.carbium.io) — A developer-facing endpoint that accepts quote requests and returns executable transaction objects. Teams building trading bots, wallets, or DeFi applications can integrate the aggregator engine without maintaining their own routing infrastructure. Authentication uses API keys via the X-API-KEY header, and the current stable version is the v2 quote endpoint.

RPC (rpc.carbium.io) — High-performance Solana RPC nodes running on Swiss bare-metal infrastructure. Carbium advertises sub-50ms latency, throughput of up to 500 requests per second, and 99.99% uptime. The infrastructure connects via direct fiber links across Europe and includes gRPC streaming support (Yellowstone Full Block format) for applications that need real-time slot and transaction feeds rather than polling.

Token Data (tokens.carbium.io) — A public API for token metadata, search, lookup, batch hydration, and cached logo URLs. This endpoint requires no API key and is designed to be embedded in frontends that need token identity resolution without managing their own indexing.

Validator — Carbium operates a Solana validator hosted on Swiss bare-metal hardware. The validator is designed around reliability metrics: a 0% skip rate is cited as a performance benchmark, and the project states that 70% of validator revenue is reinvested into ecosystem growth.

The platform also released a Carbium Agent Toolkit in May 2026 — a structured machine-readable skill file covering all seven of its infrastructure products. The file is designed for AI agent consumption, providing endpoint references, authentication patterns, use-case routing tables, and error-handling guidance that allow LLM-based trading agents to correctly configure and use Carbium's infrastructure without hallucinating endpoints or authentication formats.

SPDR Token

The SPDR token (contract address: AT79ReYU9XtHUTF5vM6Q4oa9K8w7918Fp5SU7G1MDMQY on Solana) carries utility across both the original SpiderSwap product and the expanded Carbium stack. The capped supply of one billion tokens remains unchanged from the original issuance; there has been no mint expansion.

As of mid-2026, the token trades at approximately 0.00175 USD with a fully diluted market capitalization around 1.74 million USD. The all-time high of 0.0393 USD was reached in April 2024, roughly coinciding with the live engine launch. Approximately 11,680 unique wallets hold SPDR. The token is tradeable via the Carbium DEX itself, with a SPDR/SOL pair available on Raydium.

SPDR staking remains the primary mechanism for distributing platform fee revenue to token holders, with the 15% fee allocation structure carried over from the original design. Carbium's documentation notes that SPDR also governs staking, tokenomics pages, and ecosystem participation.

Positioning

Carbium positions itself against Solana's larger infrastructure incumbents — Jupiter on the aggregation side, Helius and QuickNode on RPC — by emphasizing its Swiss jurisdiction, bare-metal ownership rather than cloud-leased capacity, and the combination of trading and infrastructure in one product family. A January 2026 DEX aggregator comparison published on the Carbium blog cited a 31ms P50 latency as a competitive metric versus hosted alternatives.

The project is founder-pseudonymous; the known handle is modsiw. There is no disclosed institutional backing, consistent with the original no-VC ethos from the SpiderSwap launch. The platform's blog remains active, with the most recent post published in August 2026.
