Lorenzo’s Multi-Vector Routing Graph (MVRG) is an advanced algorithmic framework designed to identify the most efficient liquidity paths across decentralized finance networks. In multi-chain and multi-pool ecosystems, routing liquidity is not a trivial problem: tokens can move through numerous decentralized exchanges, bridges, and lending protocols, each with its own fees, slippage, and liquidity depth. Traditional routing approaches, like Dijkstra or Bellman-Ford, quickly become computationally expensive as the network scales. Lorenzo’s MVRG solves this by representing the DeFi landscape as a multi-dimensional graph with vectorized path attributes.
Instead of a single weight per edge, each edge in the MVRG carries multiple vectors encoding key liquidity attributes: transaction fees, pool depth, slippage tolerance, execution latency, and cross-chain transfer costs. By capturing these vectors, the algorithm can evaluate trade-offs across different dimensions simultaneously, rather than collapsing them into a single scalar weight. This multi-dimensional approach enables a more accurate assessment of a path’s total cost and risk, which is critical in volatile markets.
To compute optimal paths in milliseconds, MVRG leverages several optimizations:
Preprocessing and Indexing: The graph is preprocessed to compute heuristics like maximum available liquidity per node and expected cost ranges. This allows the algorithm to prune paths that are unlikely to improve on the current best solution, drastically reducing the search space.
Vectorized Cost Aggregation: Path costs are aggregated as multi-dimensional vectors, which can be efficiently compared using dominance checks. A path A dominates path B if all cost components of A are equal or lower than B. This ensures that only Pareto-optimal paths are considered, eliminating suboptimal routes early.
Parallel Computation: The MVRG is inherently parallelizable. Multiple candidate paths can be evaluated simultaneously across CPU or GPU cores. Combined with efficient memory structures for node adjacency and edge vectors, this allows real-time computation even in dense, high-liquidity networks.
Dynamic Weight Updates: Unlike static routing graphs, MVRG can update edge vectors in near real-time based on live liquidity data, oracle feeds, and market conditions. This dynamic capability ensures that the computed paths remain optimal in fast-moving DeFi environments.
Multi-Hop Path Synthesis: In multi-chain contexts, MVRG can synthesize cross-chain liquidity paths by chaining intra-chain routes with bridge transfer vectors. It evaluates the total cost, time, and risk across all hops to select the globally optimal route for a given trade.
The result is a routing system that can identify the lowest-cost, lowest-slippage, and fastest liquidity paths across complex DeFi networks in milliseconds. By considering multi-dimensional trade-offs and leveraging parallelized computations, Lorenzo’s Multi-Vector Routing Graph enables automated market makers, liquidity aggregators, and arbitrage bots to execute large trades efficiently without manual intervention.
In short, MVRG transforms DeFi liquidity routing from a slow, heuristic process into a high-performance, real-time operation capable of navigating the rapidly changing, multi-chain blockchain ecosystem.
